How to practice this chord
- Play the F# Augmented shapes below across the neck — the same chord, in different positions, always built from F#, A#, Cx.
- Listen for how the augmented sound holds up as you move it: the notes are identical in every shape, only the voicing (which note is on top or in the bass) changes.
- Once one shape feels comfortable, move to the next — building the same chord in multiple positions is what lets you play it wherever your hand already is on the neck.
