Modern ear training Now living in a world full of technology it is easier to make up ear training tests yourself. We have the luxury of creating playlists full of MP3s with the ‘shuffle’ feature as our best friend. Another friend couldn’t tell me the names of the notes on the fretboard, but he could hear an E7#9 and label it (correctly) as a Jimi Hendrix chord. He could work out by ear and remember forty songs in one day! Thankfully we found this nice little plugin jQuery throttle & debounce plugin created by Ben Alman.
