Vocal Warmup Frequency Guide
Warm up with guided scales, arpeggios, a sustained vowel, and a siren glide. Pick your starting note and tempo, sing along to the reference tone, and turn on mic feedback to see if you’re in tune, sharp, or flat.
ℹ This tool plays sound — a reference tone through your speakers. For accurate pitch feedback, use headphones so the tone isn’t picked up by your microphone. Start gently in a comfortable part of your range and stop if anything hurts — this is a practice aid, not medical or vocal-coaching advice. The microphone is analyzed live and never recorded or uploaded; only the reference tone is produced.
The marker shows how far your pitch is from the target (centre = in tune). Best with headphones so the reference tone doesn’t leak into the mic.
How It Works
Choose a warmup and a comfortable starting note, and the tool steps through the exercise at your chosen tempo, playing each target pitch on a soft triangle-wave reference tone (an oscillator routed to your speakers). The scale and arpeggio walk up and back down; the sustained-vowel exercise holds one note; the siren glides smoothly up an octave and back. Turn on mic feedback and a YIN pitch detector listens to your voice, names the note you’re singing, and shows how many cents you are above or below the target — with an in tune / sharp / flat indicator and a moving marker.
Because the tool produces sound, headphones make the feedback far more reliable: without them, your microphone can hear the reference tone and report its pitch instead of yours. The microphone signal is analysed entirely in your browser and is never recorded or uploaded — only the reference tone is generated. Warm up gradually from the middle of your range outward, keep it light, and stop at any sign of strain. This is a practice aid, not a substitute for a voice teacher or a clinician.
