Pitch Canvas visualizes pitch as living, time-based blocks. Instead of capturing pitch as isolated points or static graphs, it forms pitch blocks that grow as the same note continues. Each block represents how pitch holds and evolves over time, creating a flowing visual record on the canvas. Pitch Canvas does not analyze, score, or correct your voice. It is designed as a visual instrument for observing pitch as it unfolds, moment by moment, as shape and duration rather than data.
