Johann Rudolph Ahle was a German composer, organist and theorist. Much of Ahle's compositional output consists of sacred choral and vocal works, instrumental music and organ music. He is best known for his Neu-gepflanzte Thüringische Lust-Garten, a collection of motets and sacred concertos.
At first sight I thought this piece was meant for one manual. But after trying different things I decided to play the cantus firmus in the pedals.
