Two Registers
Chest and head, connected by a siren you can control
Outcome: I compared two easy productions of the same pitch and could describe the audible difference.
Outcome: I followed a comfortable portion of the siren up and down and listened for continuity on each vowel.
Outcome: I sang the same short pattern on five vowels and compared the resulting tone by ear.
Outcome: I rehearsed the supplied Deep River phrase in a comfortable key and marked where my voice changed.
Outcome: I compared a relaxed baseline with a later take and described one audible change without forcing a rough sound.
Work in a comfortable range and volume. Stop for pain, burning, sudden hoarseness, loss of range or a change in your speaking voice. These lessons teach practice decisions and stop rules; they don't diagnose or treat anything, and pitch readings do not assess vocal health. Persistent symptoms belong with a qualified clinician, not another attempt.
