Pitch
Pitch is the perceptual property of a sound corresponding to its perceived highness or lowness.
Learn Generative AI with PyTorch
The perceived highness or lowness of a musical sound, determined here by the note’s frequency and encoded by pitch numbers.
- How it is used
- Represents musical note height numerically so music datasets and sequence models can process performance events.
- How deep it goes
- Explains frequency, octaves, semitones, and 0–127 pitch numbers, then applies them to MIDI events and tokenization.
- Examples
- Uses C4, F3, A4, A5, D5, and numbered note_on and note_off events.
- What you can do after
- Apply it via MIDI pitch values and distinguish note height from velocity when representing music for sequence models.

Pitch is the perceptual property of a musical sound associated with its perceived highness or lowness and position in the system of musical tones.
- How it is used
- Controls synthesizer tone generation and models pitches for musical composition.
- How deep it goes
- Explains type-class conversion, semitone tuning, chromatic notes, heterogeneous storage, and melody rendering.
- Examples
- Demonstrates concert A, octave doubling, chromatic note constructors, heterogeneous pitch lists, and a rendered melody.
- What you can do after
- Build pitch representations, convert them to frequencies, combine them in compositions, and render tones to a WAV file.
