Changing out of C♯m7
The moves below are the ones you'll meet most, shown for guitar and piano.
- C♯m7 → F♯7 (V in B major)
Guitar: C♯m7 (x-4-2-1-0-0) to F♯7 (2-4-2-3-2-2): your ring finger stays put, the index finger lays across the low E to high E strings at the 2nd fret, the middle finger goes to the G string, 3rd fret. The two chords share C♯ and E, which is why the change sounds smooth.
Piano: C♯m7 to F♯7: play F♯7 in 2nd inversion (C♯–E–F♯–A♯) and C♯ and E stay under the same fingers, while G♯ moves down to F♯ and B down to A♯. F♯7 - C♯m7 → Emaj7 (IV in B major)
Guitar: C♯m7 (x-4-2-1-0-0) to Emaj7 (0-2-1-1-0-0): the index finger slides across to the D string at the same fret, move the middle finger to the G string, 1st fret, your ring finger lands on the A string, 2nd fret. No finger can stay, so practice lifting all of them together and landing the new shape as a unit. The two chords share E, G♯ and B, which is why the change sounds smooth.
Piano: C♯m7 to Emaj7: play Emaj7 in 3rd inversion (D♯–E–G♯–B) and E, G♯ and B stay under the same fingers, while C♯ moves up to D♯. Emaj7 - C♯m7 → Bmaj7 (I in B major)
Guitar: C♯m7 (x-4-2-1-0-0) to Bmaj7 (x-2-4-3-4-2): the index finger lays across the A to high E strings at the 2nd fret, the middle finger goes to the G string, 3rd fret, the ring finger slides across to the D string at the same fret, the pinky finger comes down on the B string, 4th fret. Everything moves: lift the whole hand and place the new shape in one go. B carries over from one chord to the other.
Piano: C♯m7 to Bmaj7: play Bmaj7 in 1st inversion (D♯–F♯–A♯–B) and B stays under the same finger, while C♯ moves up to D♯, E up to F♯ and G♯ up to A♯. Bmaj7
