Welcome to the Library — every key, every frequency, tuned to order. This is the whole map of voices: deep bass hums to pocket-sized sparks, each precision-tuned in 432 or 440 Hz. The whole Library is open — every key, live at once — and every instrument here is made for you when you claim it.

🧭 Find your key: lower keys (3rd octave — F#3, G3) are deep, slow, meditative. Middle keys (4th octave — F#4 is the classic first voice) are warm and versatile. Higher keys (5th octave — F#5, D5) are bright, portable, everywhere-friendly. Minor sings inward; Dorian and Major open the door outward.
