The price includes a fingering chart, thumbrest, joint grease, and vinyl pouch.
A key over the lowest tone-hole of longer sized whistles allows small hands to easier reach the lowest tone-hole. Most players do not need a key on an -A- whistle, but often need one or more keys on the much longer low-octave models.
We can mount a key over any tone-hole of the -M- and -L- series whistles. The extra cost per key is $25.00 per key.
