I'm looking for song that would help expand my knowledge of triads. I have memorized c major shapes and having trouble on decided what to learn next.
hey Jude,
Don't make it bad,
(See what I did here) But to your question about songs using triads it's honestly endless. For instance, "Give me the Night" by George Benson, or "Brown-Eyed Girl". I'd highly recommend listening to some Larry Carlton as well, he's a melodic master and uses triads in his playing seamlessly. "Smiles and Smiles to go" and "Room 335" are famous by him but another personal favorite is "10 PM". Hope this was helpful!
