Reference tuning versus transposition

Open the interactive module

Tuning and pitch systems

Reference tuning assigns a frequency anchor to note names. A at 440 Hz is common, but ensembles may choose other values. Transposition instead moves a musical structure to another pitch level while preserving its relationships. These are different kinds of change.

If every note sits slightly above or below a recording, investigate the tuning reference first. If only certain notes disagree, examine pitches, scale context and performance. A semitone transposition is a much larger response than correcting a small reference mismatch.

Example

Changing the A reference from 440 to 442 Hz does not transpose a piece from A to B-flat.
