Tenuto is an enhanced version of the exercises and calculators for your iPhone and iPad. Each of the 24 exercises and six calculators features a friendly touch interface that is fully optimized for all screen sizes across all devices.

Tenuto requires no Internet access — continue your musical training while sitting on the bus or relaxing on the beach. Once back home or near a Wi-Fi hotspot, send an exercise progress report to your teacher.

Having a hard time with ledger lines or double accidentals? Customize each exercise to focus on your weak spots.

Challenge Mode adds a time limit or question limit to your customized exercise. Challenge yourself to beat your previous high score!

Use the calculators to compute intervals, chords, scales, and more!
