Games are an interactive and fun way to learn. Here are some online games:
The Young Person’s Guide to the Orchestra, by Benjamin Britten
Where instruments become animals in a safari! Very detailed, so get prepared to take some time to finish.
Music Learning Community
Individual games to teach specific music concepts, and comes with difficulty levels.
Quick and easy – just identify the note shown
Slightly more challenging than Note Trainer – hit the note before time’s up!
Dallas Symphony Orchestra – Kids
Quite funny – the Conductor Jump (can someone tell me what’s the point about it?)
