Pocket Ear Trainer


Pocket Ear Trainer contains randomized ear trainers for chords, intervals, and scales. Tap play and it will play a random interval, scale, or chord for you and you select what type it is. It also includes a reference and practice section so that you can read information about the sounds being played and selectively hear certain intervals, chords, and scales. Pocket Ear Trainer was created by a music educator with college music students, band directors, and musicians of all types in mind. Learning to recognize intervals by ear is a huge part of playing music by ear and as any musician or music teacher knows, an important part of overall musicianship.
