Kelischek models in high -Eb- and high -D- exist in the -V- and the -S- series. If in doubt, we recommend the -S- series as the richer and fuller sounding version. The -V- series has a slightly smaller body diameter and therefore sounds softer.

All Kelischek models have separate head and body sections with a slightly tapered bore. Pitch can easily be adjusted by pulling jointed sections in or out as needed. Unlike chromatic Recorders, Pennywhistles are diatonic instruments, requiring many sizes to make playing in all keys (tonalities) possible.

The most popular sizes used are in the keys of high -D- and low -G-. 

Body sections of the same series are interchangeable with a head section of the same series, making economical sets of whistles  available with a single head section, along with multiple bodies for playing in different keys. Kelischek two-piece models include a fingering chart, thumbrest,  and a  pouch.

All Kelischek Model Whistles are available in black or rosewood brown. 

Longer whistles can be played more comfortably with Susato Keys over tone holes too far apart for small hands. Note the Susato Keys available on low whistles, the difference in playability is enormous! All Kelischek two-piece models include a fingering chart, thumbrest, and a carrying pouch. Susato Keys can be mounted over any single tone holes that are difficult to reach on models of the -L- series whistles for an extra $35.00 per key. Keys are placed for right-handed players, but can also be mounted for left-handed playing at no additional cost. Unless ordered otherwise, all whistles are supplied without any keys.
