The NSynth dataset contains labelled audio samples from various instruments over a range of pitches. The data is prepared for use with TensorFlow and also available in JSON/WAV (metadata/audio) format. From the dataset description:

NSynth is an audio dataset containing 305,979 musical notes, each with a unique pitch, timbre, and envelope. For 1,006 instruments from commercial sample libraries, we generated four second, monophonic 16kHz audio snippets, referred to as notes, by ranging over every pitch of a standard MIDI pian o (21-108) as well as five different velocities (25, 50, 75, 100, 127). The note was held for the first three seconds and allowed to decay for the final second.
