Disclaimer

MusicReason's tools are built for musical practice, learning, and decision-making. They are not a substitute for trained ears, a music teacher, an audio engineer, or a licensed instrument technician, and none of them are certified reference instruments.

Music theory results (chord names, interval spellings, scale and key suggestions) reflect documented conventions and can legitimately have more than one correct answer depending on musical context; where that's the case, the tool says so rather than forcing a single answer.

Tuning and pitch-detection tools estimate frequency and deviation using your device's microphone and your browser's audio processing. Real-world accuracy depends on your microphone, your device, background noise, and playing technique, and should not be treated as equivalent to a calibrated tuning instrument for critical work.

Any tool that recognizes or interprets a recording (naming a chord, estimating a key or tempo from audio) reports its result using the certainty label its method actually supports, described on the Methodology page. A result is never guaranteed correct, and where more than one interpretation is plausible, the tool shows alternatives rather than a single forced answer. These tools do not identify commercial recordings, artists, or copyright ownership, and do not extract or reproduce copyrighted scores.

Production and acoustics calculations (delay time, frequency conversions, gain, room-mode estimates) are provided for planning purposes. Real rooms, systems, and equipment vary, and a calculated value should be verified against your own setup before it drives a consequential decision.

Use MusicReason's output as a well-reasoned starting point, not a final authority, and use your own judgment, ears, and (where it matters) a qualified professional for decisions that carry real cost or consequence.
