The Lark In The Clear Air might not seem much like a 'Show Off Tune'
but try doing it ib six keys on ONE whistle. If you play a C start on the E which puts you in the Key of A ,A is the start not for D , D for G, G for C, C for F and F for Bflat. The only octave jumps are the first note in each key and it NEEDS the D in the third octave when in F. Thats the note that wkes the dogs up !
