Playing by Ear
The grand mystery to playing by ear is deciding which note to start out on. If you choose that note properly, the rest of the music is greatly simplified. It also helps if you play the music in the key of C (no sharps or flats). To choose the first note, hum the last note in the song as a C. Then hum the first note in the song, and match it to the piano. This is simplified, because the starting note will typically be one of the notes in the base cord of the last note.
