***** Highly addictive piano game. ***** A fun way to develop a better musical ear! Great for experienced musicians and beginners. Music students love this app. ---- Interval Ear Training can help improve: • Interval recognition • Sense of pitch • Transcription skills • Improvising skills • Self esteem --- How to Play: • Tap "play" to hear the interval • To hear the interval again, tap "replay" • Use the piano to play the interval yourself • Play often to improve your score! --- MIDI In – Plug in your MIDI keyboard to enhance the experience! (Core MIDI compatible) MIDI Out – If you have a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI, you can play Interval Ear Training using the sounds of that app. --- Tips for the Beginners: Use the + and - keyboard range control to set the keyboard to a small range such as "C, D" or "C, D, E". Keep practicing, and as you progress you'll want to make the range larger. --- Tips for the Pros: Set "Feedback" to "Never" and turn on "Autoplay" to play continuously without ever missing a beat. Crank up the tempo to see how fast you can go! For more advanced ear training features, you'll want to Unlock Pro Settings. --- Interval Settings: Tempo – 60 to 320 BPM Keyboard Range – Starting at 2 notes in a major scale (ex. “C, D”) and up to 12 notes in a major scale (ex. “C, D, E, F, G, A, B, C, D, E, F, G”) with the ability to change octaves. Feedback – Set to "Never" to stop all messages. Set to "Wrong" if you only want messages for incorrect intervals. Sound – Set to "Piano" to hear the built-in piano sound. Set to "MIDI Out" to hear the sound of a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI. Autoplay – Turn on to always play the next interval immediately. Turn off if you want to play the keyboard freely between intervals. Key Labels – Turn off to remove note names on white keys. Allow Unison – Turn off if you don't want the same note to be played twice in a row. --- Pro Settings (requires in-app purchase): Scale – 13 major scales Difficulty - Diatonic, Random Tonic, Chromatic Length – 2 to 6 notes --- About the Difficulty Setting: "Diatonic" uses notes from a major scale. This setting is recommended. "Random Tonic" uses notes from a random major scale each time. "Chromatic" mode is the "extreme mode" where any combination of notes is possible. As a result, strange intervals like the Augmented 2nd (ex. F to G#) are possible. --- About the Score: Interval Ear Training is all about self progression. Tap the score to reset at any time. The game goes on forever and the music never ends! --- Can you guess the next note? Download the app to find out!
