Vocal Warmup Exercises — Guided Scales with Live Pitch Feedback
Practice vocal warmup exercises including 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 — a siren glide is particularly effective for waking up the vocal folds across their full range and releasing tension in the cricothyroid muscle, the same mechanism used in classical warm-up pedagogy. 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. For singers who want to explore the full span of their voice, the Singing Range Detector can map your usable range before and after warming up so you can see how the warm-up expands your comfortable reach. A typical singing warm-up session lasts 10–20 minutes, starting with gentle humming, lip trills, or a soft siren on a single pitch before moving into scales and arpeggios; these vocal exercises in this tool follow that progression naturally. This is a practice aid, not a substitute for a voice teacher or a clinician.
Breath support is the foundation that vocal exercises build on — even the best scale exercise gains little if airflow is shallow or erratic. The sustained-vowel exercise here is useful for developing awareness of breath control: if your pitch drifts noticeably on a held note, the usual culprit is inconsistent subglottic air pressure rather than a pitch-matching problem. After warming up vocally, some singers check their Vocal Fatigue Detector to monitor how steadiness changes across a session and catch fatigue before it causes strain.
