This is how it works: A roman numeral is assigned to each degree in the scale. When composers create charts to share with other musicians, they use numbers so that the musicians can play the song in whichever key is best for their instrument, band, or the vocal range of the lead singer. The numbering system works so well because it can be applied to any musical key, making it easier to transpose and understand. Other methods exist, such as the “Nashville number” method, but they all stem from the following system. This is the most common way to notate chords classically and in jazz. In a progression, chords are notated using roman numerals. Notice the chord is played only in the space of one-eighth note (on the “and” of beat 4). In this progression, the V chord is used as a passing chord from the I to the IV chord in the second bar. This chord will typically be played for one beat or less. These are called passing chords, thus named because we “pass” over them very quickly. In 4/4 time, each chord could receive two beats.Ĭhords can also be played briefly to transition from one chord to another. It’s also possible to play two chords in the space of one bar. In this progression, the i chord is played for just one bar. The progression above uses just two chords, i and iv. Therefore, the I is repeated for two bars each time the progression loops around on itself. The chords can all be the same length or different lengths.Īs you can see, in this simple 4-bar progression, all chords are of the same length, but the progression begins and ends on I.
In a diatonic scale, this produces three major chords, three minor chords, and one diminished chord (also called the leading tone).Įach chord can be sustained for any length of time, ranging anywhere from just two beats to one bar or even longer. You can learn more about keys by reading our music theory primer post.Įach musical key produces different chords, one built beginning on each note in the scale. This is called a diatonic chord progression. Usually, all of the chords in a song come from the same musical key. A chord progression (often shortened to just “progression”) can range anywhere from two chords to dozens of chords, but most common chord progressions use between three and five chords.
Simply put, a chord progression is a sequence of chords that are played in a cyclical pattern.

In this article, we’re going to dive deep into chord progressions and how to use them in your creative process. Innovation within music has largely come from chord theory and harmony over the past several hundred years, and while in recent times innovation has come from rhythm and interpolation (as in rap and hip-hop) and digital production tools, a solid understanding of chords, their properties, and how to turn them into a force for creative expression is invaluable. Learning chord theory is the most important step to exploring the musical possibilities you never even dreamed of.
