Frescobaldi was a hugely influential figure. Some of his organ works were hand copied by a young J.S. Bach for study. He was also the teacher of Johann Jacob Froberger, an equally influential composer who was studied by Bach, Mozart, Beethoven, and countless others.
this piece is so, so cool. His relationship with dissonance is so particular, so interesting, and so downright cool.
No idea what the original instrumentation would have been for this. He probably was somewhat indifferent to instrument choice, as was common in the 17th century - or he probably would've just played it on an organ.
anyway, this is how I managed to play it, and i think it's super interesting.
