Wow... you have managed to make music truly modular, in much the same way as computer programming became modular with the advent of Visual Basic.

I am fascinated by the way the "musical Legos" you have provided can be "snapped together" into many shapes, and accessorized or unified by a theme supplied by the musical arranger, complemented by his/her own accompaniment.

This new musical concept you have created is nothing short of evolutionary. If it were a living creature, it would be a whole new species.
