Seed #2999 is one entry in the Instruments 1-by-1 pillar of Calm Sound Archive. It is generated in the browser with the Web Audio API, so nothing is streamed and nothing is downloaded: the same seed number always produces the same piece of audio.
What you are hearing
Triangle tones with a breathy second partial and a slow attack, close to a bamboo flute.
The musical material uses Japanese Hirajoshi at 75 BPM, tuned to 528 Hz. A binaural offset of 1.6 Hz separates the left and right channels slightly, which is what gives the track its width on headphones.
When to use it
Use it when you want a single instrument and nothing else — no bed of noise, no percussion, no vocals. This seed leans toward study & focus and runs at 75 BPM, so it moves slowly enough to sit under conversation or sleep.

How to listen
- Press play and choose a session length between five minutes and eight hours.
- Headphones give the binaural layer room to work; speakers still play the track but flatten the stereo image.
- Keep the volume where you can still hear the room. The fade-out at the end of a session is ten seconds, not a hard stop.
