My late mother started playing piano at age 5, started giving lessons at age 7 (ten cents a lesson but this was 1921) and gave her last lesson ten days before she died. She had a classical repertoire, a lot of which was religious music, pop tunes, jazz, AND ragtime. I think her favorite was ragtime, and she always quoted Scott Joplin "do not play ragtime fast. It is never correct to play ragtime fast." When I made my tape for Marimac I got her to play backup on the Vess Ossman pieces that I fumbled through. She could sight read ANYTHING up to speed on the first time through. . . anyway were she around to vote she would vote as a ragtime fan who could do other things as well (she taught me a lot of how to "read" an audience and switch your planned program to match what's going over well) . . . so one proxy vote for ragtime!
