Summary: Modacity is a practicing app developed by Marc Gelfo, a horn player who used to be in the Hong Kong Philharmonic and who is a regular extra with the San Francisco Symphony. Modacity has become my constant practice companion. I had the chance to sit down in person with Marc here in San Francisco, and we dig into all the cool features of this app, how it is built to encourage “deliberate practice” Marc’s path from Northwestern University to eventually founding his own startup, and much more!
