Played open, the strings sound C#-C#-G#-G#-C#-C#-F#-F#-A#-A#-D#-D# – from C#2 at the bottom to F#4 at the top, a span of 2 octaves and 5 semitones.

Drop C# is re-entrant: the strings do not rise steadily in pitch, so the string nearest your thumb is not the lowest note available. That is deliberate, and it is a large part of why the instrument sounds the way it does.

Dropping 3 semitones takes the tension down noticeably. A heavier set – or at least a heavier bottom string – keeps the intonation honest and stops the low string buzzing.

History
