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!
