Samples of various instruments playing a major scale. Percussion instruments that can't play a scale play some rhythms that I made up instead.

Made using the free Sonatina Symphonic Orchestra soundfonts: http://sso.mattiaswestlund.net/ 
Some do sound rather computer generated and not all instruments are represented.

I wanted to compile a set of ear training drills for instrument recognition, but couldn't find anything with an appropriate license. So I made some samples myself in GarageBand. Now you can do whatever you'd like with them too.
