The II-V-I Progression

In the vocabulary of jazz, no phrase is more fundamental than the II-V-I. It is the cornerstone of the genre's harmonic language, a three-chord sequence of tension and release that musicians, from students to masters, have practiced for countless hours. It is the shared journey, the common tongue that connects generations of players. This design gives form to that essential movement. The iconic Roman numerals are housed within a high-contrast pennant, a geometric shape that provides a powerful sense of direction and resolution. It is a visual representation of the pull from the subdominant (II) to the dominant (V) and the inevitable, satisfying return to the tonic (I). This is a quiet, confident nod to the dedication required to master the craft.
