Acchordion vs RunOut for Discogs

Acchordion is a quiz app for learning seventh chords. Acchordion works by listening to you play your instrument (or sing) into the microphone of your device and identifying the notes you play. Match all four notes in a chord to move on to the next one. You can filter chords by their root note (e.g. C or A-flat) or by chord family (e.g. major or dominant). Why learn seventh chords? Seventh chords are the foundation of jazz and are also common in pop music. Knowing seventh chords will help you: * read music from a lead sheet * learn to play new songs more easily * make new arrangements of songs you already know * improvise over a particular song * write your own songs Acchordion is a fun way to learn these chords! It provides immediate feedback, so you can be confident that you’re practicing the right notes. Once you’ve mastered these basic chords, you’ll be ready to play like a pro!
