The original Ungar/Mason book is not optimized for mountain dulcimers. Rarely do they offer more than single-note treble notation. Their tunes range widely in key signature and, while providing chord names, there is no tab. In this adaptation, Melanie has done the work of transposing these chosen tunes to dulcimer-friendly keys (mostly D, with occasional G) and standard DAD tab (one DAC tuning). The tab fills out the chords, and allows for solo chord-melody performance. Hopefully, Melanie will continue to adapt tunes from the Ungar/Mason portfolio.
