Why Secondhand Serenade Why â?? Secondhand Serenade You can tune B up to C if you want,but it's not necessary. UPDATE: The real chords are G, C, D, and Em, so if you're going to play and acoustic version, those chords sounds better, but if it's a cover with piano and electric guitar... the fifths, gives more energy to the song, in my opinion. You can also alternate [G] [C] [D] [E] [G] [C] [D] [Em] {sot e - - - - 3 - 2 - {eot [B]G [-]- [-]5 [-]7 [-]- [3]0 [1]0 [3]2 [-]0 D 5 5 7 2 0 2 0 2 [A] (azchords.com)
