You have virtually 2-thirds of a great slice of music, but that won't be plenty. You can tell it needs to go somewhere, but you lot don't know where. Now might be the time to whip out the trusty circle of fifths, a tool utilized past composers since the early Bizarre era, to effigy out how to chart a compelling modulation.
The circle of fifths is an arrangement of key signatures and their tonal centers past perfect fifths. It is laid out so that keys located closer together in the circumvolve are more closely-related, which makes it a useful tool for charting modulations.
In this article we explore the circle of fifths and its uses, helping you have out the guesswork out of modulation in your next project.
Permit's Talk Theory
There are just a few elements of music theory worth reviewing earlier we become into using the circle of fifths every bit a tool; retrieve of these every bit the assembly instructions breaking down the patterns utilized in the formation of the circumvolve of fifths. For the music theory heads out there who already know their way around the circle of fifths, feel gratuitous to skip to the next section. Merely then again, you might detect this a helpful review.
Fundamental Signatures
Put most simply, a central signature defines a set of pitches that relate to one some other in a blueprint of half-steps and whole-steps. The major and pocket-sized modes are the most common in western music, so the circle of fifths is almost exclusively set to outline how major and pocket-size cardinal signatures chronicle to 1 another.
In the case of a major scale, the interval relationships between scale degrees follow the pattern W – West – h – West – W – Westward – h, where W = whole-footstep and h=half-step. The pocket-sized scale, on the other hand, separates scale degrees by the design W – h – Westward – West – h – Westward – Due west. For more than on these scales, see our deep dive articles on the major scale and the three minor scales.
Keys are named for the starting pitch (also known as the tonal middle or root) and the pattern or interval relationships between calibration degrees (major or pocket-sized for the purposes of explaining the circle of fifths).
The accidentals (sharps and flats) identified in key signatures are alterations of specific pitches that maintain the modal interval human relationship patterns. A major scale beginning on D, for example, requires two pitch alterations, F-sharp and C-sharp, in order to maintain the design of W – Due west – h – W – Westward – Due west – h, so the key signature for D Major volition bespeak these two precipitous pitches.

Major And Minor Keys
Major and minor keys follow different patterns of pitch relationships, just these pitch relationships are related to ane another. Essentially, re-ordering a major scale so that the root is centered on the sixth scale degree volition requite y'all a pocket-sized scale. This is the relative minor of the major scale you used to derive it. These scales will utilize the aforementioned key signature but a different root.
Because the relationship between the major and relative minor is abiding, the process used to find the relative minor is also abiding. The reverse is likewise true, meaning that the relative major of a minor key centers its root on the 3rd scale caste of the minor calibration, and both keys volition employ the aforementioned key signature. A few examples of relative keys include C Major and A modest, D Major and B minor, and B ♭ Major and G pocket-sized.
Modulations
Modulation is the movement from i central area to another. Short-term or incomplete modulations are oft referred to every bit tonicizations, which is the handling of a pitch other than the overall tonic as a temporary tonic.
In music, modulation tin can exist a useful technique for heightening drama and making a clear distinction betwixt sections of a piece of music. It is oftentimes a clearer mark of change and move than elementary chord changes that never leave a single fundamental signature. The circle of fifths is very useful in mapping modulations and tonicizations as it will aid you lot cull the nearly advisable primal to shift to.
Sharps and Flats
With the circle of fifths, the tonal centers of the keys motion in perfect fifths from one key to the next, simply the key signatures move just ane accidental at a time. For example, C Major and A minor are typically listed at the top of the circle of fifths. As we move to the right (clockwise), we add one sharp with each primal, then the next keys are G Major/E small-scale, the keys with one sharp.
Moving 1 more key to the right we land on D Major/B small-scale, with 2 sharps. The process continues, with each new key calculation an additional sharp and centering the root a perfect fifth above the root of the previous key.
If we return to C Major but then move to the left (counter-clockwise), we land on a key signature with 1 apartment, F Major. F is a perfect 5th below C. If nosotros move one step further to the left we land on B-flat Major, with two flats. This pattern continues as well, with each additional pace to the left landing us an boosted flat in our key and centering our root one perfect fifth lower (or one perfect fourth higher) than that of the previous cardinal.
This is an of import distinction to annotation: moving clockwise around the circumvolve of fifths results in ascending past perfect fifths (C – G – D – A – E – B – F ♯ – C ♯ ). Moving counter-clockwise, even so, results in descending by perfect fifths or ascending by perfect fourths, depending on your perspective (C – F – B ♭ – E ♭ – A ♭ – D ♭ – G ♭ ).
The perfect fifth is the inversion of the perfect fourth, pregnant that a movement in one direction will exist inverted in the opposite direction. In this manner, the circle of fifths could exist conceived as the ascending circle of fourths if read counterclockwise, or the descending circle of fourths when read clockwise.
Each of the major keys has its own arrangement of sharps or flats, and the order in which accidentals is added follows a blueprint: the club of sharps is F ♯ , C ♯ , Thousand ♯ , D ♯ , A ♯ , East ♯ , B ♯ , whereas the lodge of flats is the contrary of this pattern: B ♭ , E ♭ , A ♭ , D ♭ , Grand ♭ , C ♭ , F ♭ .
Why A Circle?
Thus far we have detailed the circumvolve of fifths in a somewhat linear way: motion to the right and add a precipitous (or remove a flat) and move to the left to add together a flat (or remove a sharp). So why do we lay central relationships out as a circle? The respond is clearer at the lesser of the circle, as we come across the overlapping keys of D ♭ /C ♯ Major, G ♭ /F ♯ Major, and C ♭ /B ♯ Major.
While nosotros could conceive of primal relationships in a linear manner, from seven flats to seven sharps and all of the keys in between, we would so miss out on the fact that several of the keys at the extreme ends of the slope are enharmonically-related, meaning that they are the exact aforementioned keys simply spelled differently. For that reason, we lay the keys out in a circle and retrieve of harmonic motions as moving counter-clockwise and clockwise around the circle as opposed to leftwards or rightwards on a line.
Nosotros are of course already familiar with musical pitch being cyclical – once we accomplish the next octave, the notes in a scale repeat an octave higher.
Closely (And Distantly) Related Keys
Part of the fine art of crafting music is balancing similarity and divergence. Too much sameness can make for tiresome music, whereas also much divergence tin make it hard for an audience to find their footing.
Nosotros see this dichotomy repeat throughout the practice of composing music. Whether it be in utilizing inversions to take reward of mutual tones and maximally smooth phonation leading or the use of melodic and rhythmic motives that render frequently enough to help ground the listener's attending merely non so frequently every bit to bore them.
Part of what makes the circumvolve of fifths 1 of our most useful resources for composition is that it is substantially a roadmap connecting key areas in terms of how closely they relate to one another. Keys that neighbor one another, for example, share every pitch except for 1, meaning that they are very closely related. Keys located directly across from each other on the circumvolve share no common pitches, meaning that they are very distantly related. In the next section, we will go into why this is so useful.
The Circle Of Fifths Beyond Cardinal Relationships
Some theorists will point to the use of the circle of fifths in theoretical questions unrelated to fundamental signatures, such as edifice triads. While the system of pitches in perfect fifths does make information technology possible to map relationships other than those between fundamental areas, the circle of fifths is a fairly clunky tool for doing theoretical work beyond simply mapping key relationships. For a useful tool in constructing triads and visualizing their relationships, look into the tonnetz.
Even for the piece of work of mapping key relationships it starts to lose some of its handiness when it comes to modulations that are non based on perfect-fifth relationships, such as those initiated through macerated pivot chords. For these modulations, the best the circle of fifths tin can do for usa is to prove us that they are distantly-related; information technology cannot do anything to tell usa why the modulations seem somehow to work.
Information technology is situations similar these in which a music theory tool is non a particularly effective means of explaining why something sounds good. So we have to be on our guard that the belittling tool does not take on the office of a gatekeeper. Music theory and all of its limitations should never have precedence over making good music.
A Helpful Reference Tool
The circle of fifths is a collection of patterns that tin can be a tremendous help in keeping rails of where the patterns intersect. For instance, given one variable, such as the name of a primal, and the agreement of how sharps and flats are ordered in the circumvolve of fifths, it is possible to determine how many sharps or flats brand upwards that key.
Inversely, given the number of sharps or flats in a key and the understanding of how roots progress up a fifth for every step in clockwise movement and down a fifth for every step counterclockwise, information technology is possible to determine the name of a cardinal.
Just like any tool for making and dissecting music, the more i uses it the less i needs to reference it, but the circle of fifths can prove invaluable early on in making sense of music theory.
Modulations: Where Exercise Nosotros Become From Here?
Whether we're building a modulation path that traces the circle of fifths exactly or only moving to the dominant key area before a anticipated return to the tonic, the circle of fifths has a lot to offer u.s. in presenting key areas in a style that clarifies the degree to which they are related to i another.
The following compositional techniques depict direct from the circle of fifths, but the list is far from exhaustive. I encourage you not only to brand apply of these techniques but also to think outside of the box and find other ways to approach the circle of fifths beyond the standard uses.
Modulation To A Relative Key
The first technique we will explore has null to do with perfect fifths; rather, the relationship betwixt a major fundamental and its relative small-scale. With both central areas sharing the same key signature, this makes the modulation from a major key to its relative minor, or vice versa, a adequately polish transition. In western art music, the transition from a major fundamental to its relative minor cardinal is often cued with a raised leading tone in the minor central area. Other than that, there is no alteration of the fundamental signature, since relative keys share the same central signature.
One instance of the modulation to a relative primal tin can be heard in "One" by U2, in which the verse is in A pocket-sized but the chorus has a chord progression set in C Major.
Modulation To The Dominant
A dominant primal relationship exists between any given key and the central found i pace clockwise on the circumvolve of fifths. A modulation to the subdominant does non require much grooming, since both the tonic fundamental and the dominant key each share six of their seven pitches. A particularly transparent instance of a modulation to the dominant cardinal area can be heard in Queen's "Save Me," in which the song begins in Yard Major, but modulates to D Major for the chorus earlier modulating back to G Major.
I say this modulation is transparent because there is something of an abrupt pause before we hear the starting time chorus in the ascendant key. Knowing Queen'south fashion, this is by design and meant to heighten the drama. For anybody hoping to arroyo the dominant fundamental area more than smoothly, nevertheless, there is the secondary ascendant.
The secondary dominant is the dominant chord of the key you are approaching, which helps to reinforce the modulation by serving as a sort of middleman helping to introduce the new tonic.
If, for case, you were hoping to modulate to the dominant of C Major, which is G, yous could use the V chord in G to reinforce the inflow of K as the tonic of a new central area. This would exist a D Major chord, which is distinct from the ii chord in C, D minor, because it features an F-sharp, the leading tone in One thousand Major, every bit its chordal third. This inflow of the F-sharp implies a resolution upwards by step to G and thus helps to prepare the arrival of the new tonic in the modulation.
This use of the secondary dominant is non express to modulations to the dominant; in fact, a secondary dominant can be used with varying degrees of smoothness in any modulation.
Modulation To The Subdominant
A subdominant cardinal relationship exists between whatever given primal in the circumvolve of fifths and the key establish one footstep counterclockwise. Much like in the case of a modulation to the dominant, both the tonic central and the dominant key each share vi of their seven pitches, thus there are relatively few steps required to get from one to the other. 1 particularly well-known example of a modulation to the subdominant tin can be heard in the bridge section of The Beatles' "I Want To Agree Your Manus."
While the remainder of the vocal is in G Major, the bridge moves to C Major, as is made clear through the D minor chord that begins the accompaniment to the phrase "And when I touch you." The F-natural in the D minor chord does not belong to the fundamental surface area of Grand Major, but it fits correct into the key of C Major.
Descending Fifths
Don't Shoot The Pianist recently put out a new cartoon entitled "How Composers Modulate" in which the first instance features Bach proceeding from the "one-time" key through an arch labeled "circle of fifths" to the "new" key. The implication is that Bach moves through much of the circle of fifths via an ascending or descending fifths progression in order to arrive at a new cardinal.
The way the descending fifths progression works is to brainstorm with a chord built on whatever tonic, then progress to the chord built on the pitch a fifth below the original tonic (the key area one step counterclockwise), then echo the procedure from the new home chord, until you have reached your destination. It is possible to travel all the way effectually the circle of fifths this way until you reach your original habitation chord or to get off the ride a scrap early through either a chromatic alteration to speed the process of returning dwelling. It is as well possible, as in the example from the comic, to arrive at your "new key" destination.
The ascending fifths, or ascending fourths, progression is essentially the same with a clockwise motility through the circle of fifths as opposed to the counterclockwise motility.
The example beneath is non Bach but Purcell, yet for fans of Wes Anderson it might be more familiar every bit the theme quoted by Benjamin Britten as part of The Young Person's Guide to the Orchestra, which Anderson used to frame the soundtrack to Moonrise Kingdom (2012). At any rate, Purcell places a descending fifths progression prominently subsequently the kickoff few seconds of the slice.
There are countless examples from Bizarre music in which this is an accurate depiction of how composers attune, but one demand non go back so far to find the descending fifths progression. One well-known example is "I Will Survive," a tune first popularized by Gloria Gaynor just after reinterpreted past Cake and Demi Lovato, among others. The chord progression for this tune is another classic descending fifths progression.
