Vocal Range Finder – Match Your Voice to Notes on Piano

Vocal range refers to the span of musical notes that a person can produce with their voice, from the lowest sustainable note to the highest. It is typically measured in octaves and semitones. Knowing your vocal range helps you choose songs that suit your voice, identify your voice type (e.g., soprano, tenor, bass), and train more effectively.

This tool uses your device's microphone to capture your voice in real-time. An autocorrelation pitch detection algorithm analyzes the audio signal to determine the fundamental frequency. The detected frequency is then mapped to the nearest musical note on a standard piano keyboard (A4 = 440 Hz). The corresponding piano key highlights instantly, showing you exactly which note you're singing.

• Bass: E2 – E4 (approx. 82–330 Hz)
• Baritone: A2 – A4 (approx. 110–440 Hz)
• Tenor: C3 – C5 (approx. 131–523 Hz)
• Alto/Contralto: F3 – F5 (approx. 175–698 Hz)
• Mezzo-soprano: A3 – A5 (approx. 220–880 Hz)
• Soprano: C4 – C6 (approx. 262–1047 Hz)

These are general guidelines. Individual ranges may vary. Your voice type also depends on timbre, tessitura, and passaggio points.

To find your full vocal range: 1) Warm up your voice with gentle humming. 2) Start from a comfortable middle note and sing descending notes slowly until you reach your lowest sustainable note. 3) Then sing ascending notes from the middle until your highest comfortable note. 4) This tool automatically tracks your lowest and highest detected notes during a session.

The average untrained singer has a vocal range of about 1.5 to 2 octaves (18–24 semitones). Trained vocalists often extend their range to 2.5–3 octaves or more. Exceptional singers like Freddie Mercury and Mariah Carey were known for ranges exceeding 3.5–4 octaves. The key is consistent practice and proper technique to safely expand your range over time.

Several factors can affect accuracy: background noise (try a quiet room), microphone quality (use a decent external mic if possible), singing volume (sing clearly and at a consistent volume), and environmental reverb (avoid echoey spaces). Adjust the sensitivity slider—lower sensitivity filters out more background noise. Also ensure your browser has permission to access the microphone.

Yes! This tool is fully responsive and works on mobile devices. Simply allow microphone access when prompted by your browser. For best results on mobile, hold the device fairly close (about 15–30 cm from your mouth), use in a quiet environment, and ensure you're on a secure HTTPS connection (required for microphone access on most browsers).
