Progressions in G# — Cello

Every chord the key of G# owns, mapped along CGDA by finger and position.

G# major harmonises to G# – A#m – Cm – C# – D# – Fm – G°; G# minor to G#m – A#° – B – C#m – D#m – E – F#. Each chord links to its tone map on the Cello, so a tune in G# becomes a short list of places the hand needs to be.

The useful question in a key is which open strings it agrees with. In G#, check the chords against the open C and A — a key that leaves an open string ringing under the melody is a key this instrument was built for.
