"All Cows Eat Grass" is a mnemonic used in music instruction for A C E G�the notes on the white spaces of the bass clef. The All Cows Eat Grass project is an online platform that provides cost-effective, real-time private music lessons. The system connects music instructors and students using a low-latency audio and video link, provides motivational support to practice between lessons, and lowers the barrier to learn music with self-instruction material and self-evaluation musical games.
