Caden did wish, idly, that he was better at the piano. Not Lucien Rameau levels of better; just good enough that he could improvise some complementary tune to accompany Coby's playing and singing.

But Caden's voice had always been his best instrument, and he could do something with that. Once he'd got a good enough idea of the melody, he harmonised with Coby, humming along a counterpoint that worked beautifully with the song. His gaze switched several times from Coby's hands to his face, watching him play, watching him sing, and there wasn't a hint of self-consciousness in Caden.
