H1, H3, and H5 harmonics for singers
Harmonics turn a pitch reading into a voice picture. H1, H3, and H5 are simple checkpoints for comparing the same note across different attempts.
H1 is the center
H1 is the first harmonic and usually lines up with the pitch. It helps you see where the sung note begins before the rest of the spectrum stacks above it.
H3 and H5 show tone changes
H3 and H5 can become clearer, weaker, or more uneven when closure, vowel, volume, or microphone position changes. They are not moral scores; they are comparison points.
A practical exercise
Sing one comfortable note on AH. Capture the graph. Then sing the same note slightly breathier and slightly firmer. Compare how H3 and H5 respond.
What not to assume
A strong H5 is not automatically better singing. Style, comfort, and repeatability matter more than one bright peak.
How to check this in the analyzer
Choose one note, one vowel, and one microphone distance. Capture the graph before and after one small change. Start by comparing pitch stability, then H1/H3/H5, then F1/F2/F3 candidates.
This is practice feedback, not medical diagnosis or a final technique label. The best result is a sound that is comfortable, repeatable, and useful for the music.
