Know your notes.
Hear the difference.
Reference tones can support ear training, pitch comparisons and music experiments. A tone generator gives you a sustained audio point of reference while exploring sound.
Why this matters.
Daikyouju Tone Generator Professional is a focused signal-generation utility. Check the current App Store listing for the supported controls and compatibility.
Practice note: Keep the playback level comfortable, especially with headphones or sustained tones.
A better way
to get in tune.
Follow these steps using the app and your instrument. They are general guidance, not a claim that every interface has identical buttons.
01
Choose a reference
Decide which note or pitch standard is required for your practice or ensemble.
02
Open the reference-tone app
Select an available pitch or frequency in the app. Available controls can differ by version.
03
Set a comfortable volume
Start low, especially with headphones and sustained tones, and increase only as needed.
04
Listen, compare and adjust
Play or sing your own note after the reference. Compare carefully rather than trying to match by force.
05
Check without the display
After several repetitions, try to identify the reference using your ear before checking a visual tuner.
