A short article documenting the interplay between music and mathematics, with a bibliography. Explorations into tunings include why there are twelve tones in an octave, tuning problems that lead to the Riemann zeta function or to logarithms, nineteen-tone tunings, and the theory of chords. Odds and ends in the More Math-'n'-Music topic include connections between music and the learning of math, appearances of the golden mean and sums of series in music, defining musical styles mathematically, the psychology of music and other interplays between math and music, a combinatorial partition problem, and personal tidbits about Chopin, Bartok, Birkhoff, and other composers
