Get your Ear out of the dark. The BEST way to learn ear training is through immersion. That's where complete ear comes into play. ---Lesson Preview-- In Practice mode, you select the interval or chord sound you want to hear and let it loop. With each loop you will be gradually increasing your ears ability to recognize that interval. You could even sing along to match the interval. You can do this anywhere with headphones and spare time to listen. When you feel you have familiarized yourself with the note relation then head over to Test mode. You should practice your intervals and chords until the each are obvious to your ear. When testing you should strive for an immediate response, if not continue practicing. Every practice compiles your ability, so be diligent. Focus on Intervals before Chords. With Complete Ear you will have the resources to develop an all around ear. Practice - Listen to Intervals to build a relational understanding of them. Sing along to master a specific interval. Choose to practice between: -Separate Intervals -Harmonic Intervals (Played at once) Test - Put your practice to the test with fully customizable settings. Choose between: -Separate Intervals -Harmonic Intervals (Played at once) -Only intervals down -Only intervals up -Randomly up or down played intervals Complete Ear is the All-in-One ear training app that every musician and singer should have in their musical arsenal.
