TheSingingMixer: #Bach's #OSacredHead is a glorious #hymn that @jecissalynn has brought to #acapella #8part #vocalbliss! I'm joining her to #collab with a #mashup of #PaulSimon's #AmericanTune (2nd verse if your keeping track) which I think he wrote inspired by this #chordprogression. It works so perfectly, it has to be! If anyone wants to grab this & add #instruments to #joinmycollab (add extra squares?), feel free! It's absolutely #gloriousmusic! #tsm
