Progressions in F# — Violin

F# major harmonises to F# – G#m – A#m – B – C# – D#m – F°; F# minor to F#m – G#° – A – Bm – C#m – D – E. Each chord links to its tone map on the Violin, so a tune in F# 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 F#, check the chords against the open G and E — a key that leaves an open string ringing under the melody is a key this instrument was built for.
