Speciality Whistles
My whistle and instrument workshop has been closed for some years.
I am very sorry, but not able to offer any new whistles!
D-Plus-Whistles with 7 finger holes for additional bottom C
Gypsy-Whistles (in any key) for harmonic and double harmonic minor and related modes
See also: Standard Whistles - standard diatonic whistles with six finger holes (or seven with optional thumb hole).
