The KDM Focus is on using the "C" and "D" Celtic Whistles for many of the arrangements. The following shows the commonly used C and D whistle scales with suggested tone hole tabs.
The KDM Initiative also occasionally uses the Richter-Tuned, 10-hole, Diatonic Harmonicas to play some of the selections. The following shows the notes with these types of instruments. Unlike the Celtic whistles with alternate fingering, diatonic harmonicas are "RESTRICTIVE" in that it is very difficult to fake any type of chromatic notation without "bending" the open reeds. Usually, the player switches out diatonic reed harps for differing scales.
