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.
The idea for this site is that it will offer a range of aural skills activities and exercises that complement any collegiate-level music theory sequence. EarStrainer could also fit the curricula of aggressive high-school music programs, but the activities aim to serve the needs of undergraduate aural-skills classes, ranging from fundamentals through 21st century music.
I work on this site in my spare time. Be patient, please.
