10-Minute Pitch Calibration

SingMeter tools for this lesson

Step-by-step practice

1. 1

   Pick your starting note

   1 min

   Use a note in the middle of your comfortable range—often C4 for many voices, or G3/A3 if C4 feels high. If you completed the Vocal Range Test, choose a note about halfway between your low and high results.

2. 2

   Play the reference (Tone Generator)

   2 min

   Open Tone Generator, select sine waveform, set volume to 30–40%. Play your starting note (e.g. C4) for 3 seconds. Listen without singing. Stop the tone, wait 2 seconds, then play it once more—this trains your ear before you vocalize.

3. 3

   Sing and match (Pitch Detector)

   3 min

   Open Pitch Detector in the same browser (new tab is fine). Start listening. Sing the same note on a steady “Ah” for 4–5 seconds. Watch the cents indicator: • Near 0 = in tune • Negative = flat (add support, slightly higher placement) • Positive = sharp (relax jaw, less push) Repeat until you hold the green zone for at least 3 seconds.

4. 4

   Second note: major third or fifth above

   3 min

   Return to Tone Generator. Play a note a major third above your start (e.g. C4 → E4) or a fifth (C4 → G4). Again: listen twice, then sing on the Pitch Detector without sliding up to the note—land on pitch cleanly. If you miss, replay the reference once only, then try again (avoid “scooping”).

5. 5

   Cool-down check

   1 min

   Return to your starting note. One final hold on Pitch Detector. Note which direction you tend to drift (flat or sharp)—write one word in your practice log. Tomorrow, bias your correction in that direction.
