## What is OtoMaster?

OtoMaster takes its name from the Japanese word “oto” (音), meaning “sound.”

OtoMaster is a music training app that helps you practice note reading and ear training using note cards and an on-screen keyboard.

See a note on the staff and answer on the keyboard.
Listen to a note and identify its name and pitch.

With simple exercises you can practice anytime, OtoMaster helps you build the basics of reading music and improve your ability to recognize notes by ear.

【Note Reading with the Keyboard】
Look at a note card and select the matching note on the on-screen keyboard.

・Treble clef
・Bass clef
・Random exercises across treble and bass clefs
・Sharps and flats
・Selectable note range
・10–60 second time settings

You can display note names on the white keys as Do Re Mi or C D E.
Even if you are new to reading music, you can practice at your own pace.

Your score is based on correct answers, accuracy, and response speed.
Review your best score and recent play history, and challenge yourself again and again.

【Ear Training】
Listen to a single note and first select its note name on the keyboard.
Then choose the note card that matches the correct pitch.

“You know it’s a C—but which C is it?”

Practice identifying both note names and their pitches through repeated exercises.

Exercises can also include sharps and flats.

【Practice Your Way】
・Choose the note range for note-reading exercises
・Enable or disable sharps and flats
・Choose the time limit
・Choose the number of ear-training questions
・Display Do Re Mi or C D E on the keyboard
