Practice Pitch Accuracy with Real-Time Feedback

This tool combines the power of AudioWorklet-based pitch detection with structured practice. A target note is displayed, and you must sing or play that note on your instrument. The real-time pitch detector shows exactly what note you're producing and how close you are to the target.

Tip: Start with a comfortable octave range (C3–C5). Focus on holding a steady pitch rather than hitting the note immediately. The hold-for-1-second mechanic encourages sustained accuracy.

Pitch Practice — Frequently Asked Questions

Find answers to common questions about our virtual instruments, practice tools, and music theory workspace.

How does pitch practice work?

A target note is displayed.

You sing or play that note into your microphone. The pitch detector analyzes your audio in real-time and shows which note you're actually producing. Hold the correct pitch within 20 cents for 1 second to score.

Do I need a microphone?

Yes.

The pitch practice tool uses your device's microphone to detect the pitch you're singing or playing. Works with built-in laptop/phone mics, USB mics, or instrument pickups.

What notes can I practice?

You can select any range of notes from C2 to B6.

The default range is C3 to C5 (the typical vocal range). You can also filter by note names (e.g., only natural notes, or only specific notes).

How accurate is the pitch detection?

The AudioWorklet-based autocorrelation pitch detector achieves ±1 cent accuracy in quiet environments.

For best results, practice in a quiet room and hold your note steady.

What does 'within 20 cents' mean?

A cent is 1/100th of a semitone.

20 cents = one-fifth of a semitone. If you're within 20 cents of the target pitch, the detector considers it a match. This is a reasonable tolerance for ear training.

Can I use this to practice singing?

Absolutely.

This is an excellent tool for vocalists to practice pitch accuracy. Sing the target note and the visual feedback shows you whether you're flat, sharp, or on pitch.
