Believe Me if All fits on a bagpipe, since the compass is one octave, and the missing notes (like G#) can safely be ignored. But a tune not composed with the pipes in mind can be a regular bugger to fit! Especially when the compass is far beyond the nine notes of the bagpipe scale. I shudder to think what the result might be... The "Major Graham" in SMM (and hence in the Oxford Poems and Songs, edited by Kinsley, 734) goes from middle C to top G, which the pipes can't handle. The tune mostly used, mind you, these days is "Low Down in the Broom", also in SMM, no. 90.(or an adaptation thereof), which has an even wider compass. I don't see how these can be played on the pipes at all. I'd be interested to hear how this is managed.
