A chord progression is a series of chords that are constructed from scale degrees (usually Major and Minor scales), and then played in succession, usually repeated over and over again throughout a song. Chord progressions have tonal centers and can be thought of as ’modal’ in nature.
The Modal Alchemist completes Robbie's trilogy of courses focused on the modal approach for identifying tonal centers, building chord progressions, and crafting compelling solos over virtually any progression. In Modal Expose, Robbie showed you the seven modes that live within the seven notes of a major scale. He then revealed how major, minor, dominant and diminished arpeggios and chords are built from those seven notes and modes within that key. Using Robbie's simple "modal" formula you learned how to quickly grasp the underlying harmony of any chord progression. To ice the cake, Robbie showed you how to apply your newfound understanding of modal harmony to improvise melodic lines seamlessly across any set of chord changes, in any progression, in any key.
