EarStrainer.com is an online ear-training portal built by Brian Bondari. The goal is to provide a free and accessible online alternative to commercial ear-training software packages. Unlike these commercial packages, which have a significant upfront cost and are only available on a limited number of machines, EarStrainer is accessible from any Internet-enabled computer.

What we offer is a range of aural skills activities and exercises that complement any collegiate-level music theory sequence. EarStrainer can also fit the curricula of aggressive high-school music programs, but our activities aim to serve the needs of undergraduate aural-skills classes, ranging from fundamentals through 21st century music.
