Vibrato Test: Measure Your Vibrato and Practise Controlling It
Hold any comfortable note for five seconds and DailyVocal measures your vibrato: its speed in waves a second, its width in cents either side of the note, and how regular it is. Most trained vibratos run at about 5 to 7 waves a second. Then a short control drill asks you to hold a straight tone for three seconds and let the vibrato in for three more, the skill choirs, musical theatre and pop singers all need. Your last two weeks are kept in your browser so you can watch it change. Free, no account, nothing recorded: only the pitch is read.
