Piano Melody Free

Piano Melody Free is a keyboard app intended to help anyone learn to play the piano by ear. Students select a song (songs with titles through the letter "C" are included; accurate playing can unlock other songs on the extensive list), hit the play button to listen to the selection, and listen to a series of sounds as the corresponding notes light up on the keyboard. Students then play the same series of notes and hit a check-mark button to get feedback. A dialog box pops up with the result, listing the correct notes (such as "C4," "C4," "G4," "G4," "A4," "A4," and "G4" for "Twinkle, Twinkle, Little Star") and the notes the student played. If the series played is correct, the student can proceed to the next portion of the song to learn further notes and phrases. 

Individuals can customize their experience to better suit personal ability and pace; they can change the number of notes they hear in each sample, the playback speed, the size of the keys, and the labels on the notes. They can also change which section of the keyboard is visible using a selection tool near the top of the screen. Although few songs require playing multiple notes at once, the keyboard does so capably.
