Ear Logic - Ear Trainer for Guitar app for iPhone and iPad

Ear Logic is a customizable ear training app designed to help guitarists build the musical connection between their ears and the instrument. Ear Logic goes beyond simple interval and scale recognition training, and instead trains you to instinctively know where a sound exists on the fretboard.

All ear training test responses are given through the fretboard. The ear training exercises are always in the context of a chosen key and scale. This allows you to associate the sound of an interval to its position in the scale and location on the fretboard.

Ear Logic is also a powerful fretboard visualization tool that displays scale shapes, intervals and note names. Performing ear training while also displaying the scale shape helps you build an association between a given sound and its location in the scale shape. You can also simultaneously view a second reference scale shape, allowing you to see the common notes between keys and scales, which helps when improvising over chord changes.

Learning to recognize musical intervals and scales requires listening to these sounds many times. Ear Logic has a playable fretboard and can play the selected key and scale in the region of the fretboard currently in view. This allows you to practice listening to the sound of these intervals and scales when you are away from your guitar.

Ear Logic’s scale visualization can also serve as a helpful fretboard “roadmap” when practicing, allowing you to see the scale shapes and intervals while improvising.
