Flash Chord



Flash Chord is a free online tool for musicians who want to practice chords, scales, or arpeggios with an endless stream of randomized chords. Learning a song or practicing to a backing track is great, but if you really want to learn your instrument, you need to be ready for the unexpected. With Flash Chord, you can specify the speed and complexity of the chords being presented and you'll never know more than one chord in advance.


Now that you've got the idea, let's setup your Flash Chord practice session for success!

  1. Tempo - Use the slider to adjust the speed of the incoming chords. Slower tempos mean slower chord changes.
  2. Time Signature - Set the time signature to specify the beats per measure.
  3. Key - Select the key in which you'd like to practice your chords or, for a real challenge, leave the key set to Any to see chords from any key.
  4. Difficulty - Select the complexity of the chords being generated:
    1. Beginner: major, minor, 7, minor 7
    2. Intermediate: maj7, 6, m6, sus2, sus4, 9, m9
    3. Advanced: +, °, m7♭5, 7alt, 6/9, 11, 13
    You can also specify if you want additional extensions (♯5, ♭5, ♯9, ♭9, ♯11, ♭13) added to the chords by checking the Add extensions checkbox.
    If you really want to kick it up a notch, check the Hide next chord checkbox to get the next chord without any warning!
