I don't play my Folkcraft chromatic dulcimer that much because I previously only had one chromatic book, which Folkcraft also sells, so I decided to buy the collection of "Speakeasy and Tin Pan Alley Tunes" by Dana Gruber. The selection includes songs that are familiar to me and many that are not. Initially, I stumbled playing the arrangements because the book uses the diatonic fret numbering system with half frets rather than the chromatic system. I even start penciling in the chromatic tab under the diatonic numbers for nearly half the songs, which helped me to understand how the two systems compare and contrast and memorize, for example, that 5 in the diatonic system is 9 in chromatic. Then I realized it was actually easier to play the diatonic numbers instead of looking at a larger set of numbers. After all, most diatonic players are familiar with the 6+ fret and likely the 1+ fret as well. From there, it's just a matter of adding the 0+, 3+ and 4+ frets. I quickly got the hang of playing familiar songs such as Alexander's Ragtime Band with the diatonic system and began erasing the chromatic numbers I penciled in. Having the extra notes enables jazzier arrangements, especially since the tunes contain plenty of chords. If you have a chromatic mountain dulcimer, enjoy playing music from the early 1900s and are looking for songs arranged for that instrument, I highly recommend this book. I know my chromatic dulcimer is not going to gather as much dust moving forward.
