Octave
An octave is a musical interval between pitches whose fundamental frequencies have a two-to-one ratio.
Learn Haskell by Example
An octave is a musical interval spanning a frequency ratio of two to one.
- How it is used
- Uses octave relationships to validate pitch calculations in a digital music synthesizer.
- How deep it goes
- Defines octave doubling and halving, then checks it through semitone calculations and a proposed QuickCheck property.
- Examples
- Uses concert A at 440 Hz, semitone offsets of 12 and −12, and GHCi frequency calculations.
- What you can do after
- Apply octave relationships through Haskell frequency calculations and test them as formal properties.

The distance between one level of musical pitch and the next, where frequencies double from one octave to the next.
- How it is used
- Explains how musical pitch is organized before encoding music for machine-learning datasets.
- How deep it goes
- Defines octave frequency and subdivisions, then connects them to pitch numbers, without developing acoustic theory or model internals.
- Examples
- Uses middle C, C4, F3, A4, A5, frequency values, and pitch numbers as concrete examples.
- What you can do after
- Apply octave levels and pitch numbers to interpret notes and structure digital music data.
