I thought about this too. Multiple choice A, B, C, etc... just play the chord. :)

But that's pretty challenging from an engineering standpoint and Alexa skills can't be controlled externally yet. I briefly added a footswitch and could get Thingamagig to cycle through the tones of a particular song with it, but the Alexa screen won't update on that "outside" information.

Amazon has said they'll consider it but my gut says that's way down the list of things they're trying to do.
