Double Harmonic Major – mDecks Music
An applied deep-dive into the Double Harmonic Major scale: its interval formula, tetrachord structure, modes, and how to use it on keyboard, guitar, and in improvisation.
This lesson maps the Double Harmonic Major scale from a random-interval exercise onto the circle of fifths and the keyboard, showing the intervallic formula and tetrachord structure that define its "double harmonic" character. It demonstrates how rotating the shape on the circle of fifths generates the scale's modes (e.g., Hungarian minor, Ultra Phrygian), and explains practical applications for keyboard and fretboard, chord implications, and dissonance analysis. The lesson includes a listening/improvisation example and walks through steps and motivic ideas for using the scale in modal, quasi-tonal contexts.
