Hear how instruments make music.

Start with how sound is made, then compare orchestral, world, electronic, and classroom labels.

Use visible pitch geography for steps, skips, intervals, chords, and transposition.

Connect fifths, scale degrees, interval size, and harmonic function to the sounds learners hear.

Learners sort by vibration source, controller, resonator, and signal chain instead of memorizing families.

Each instrument carries a physics, language, history, geography, or coding transfer target.

Instrument cards connect to mic, DI, mixer, patch, amp, filter, and safe-listening decisions.
