Why short sessions work better
Your mouth muscles and breath tire faster than you think. Fifteen focused minutes a day build steady progress, while one hour a week mostly builds frustration.
Week 1: a steady basic tone
Aim for a clean sound without extra vibration. Record every attempt in the app and compare it with the reference in overlay mode.
Week 2: volume control
Practise moving from a quiet call to a loud one and back. Watch the duration metric — it shows how steadily you hold the note.
Record everything. Your ears lie; the spectrogram does not.
Weeks 3 and 4: phrases and variation
Build a short phrase from three or four elements and repeat it at different tempos. Compare individual metrics, not just the final score.
