MODUS HARMONI FIRST DRAFT

MODUS HARMONI.

Build your own chord progression, choose a key and scale, and hear how the chords fit together. Select a chord to see its notes and how to play it on guitar or piano.

01 / YOUR CHORD PROGRESSION

Choose a chord. Make it yours.

Click a chord card to see its shape. Change the root and chord type directly in the card.

TONAL CENTRE AND SCALE MAP

A new tonic transposes the whole progression. A new scale adapts the chords on the same degrees. Roman numerals show degrees from the tonic, using major-scale degrees as the reference. Lowercase means minor. ♭ and ♯ indicate lowered and raised degrees.

INSPIRATION / READY-MADE PROGRESSIONS

Start with a familiar progression.

Choose a progression to insert its chords automatically. You can edit them freely afterward.

4 beats per chord · 4/4

02 / FROM THEORY TO SHAPES

Guitar

X = muted · O = open string
Green = root · line = barre

Piano

Play the highlighted keys together. An inversion changes the bass note, while the root remains highlighted in green.

The piano shows its own voicing of the same chord. The guitar may double notes, omit the perfect fifth and use a different register.
