 Kerll's influence was perhaps short-lived compared to Froberger's (the most important fact here being Händel's frequent borrowing from Kerll's work), but he was a model (perhaps even taught) for the Nuremberg-born Johann Pachelbel, whose work is the highest point of the south German tradition.Typical south German organs differed from their northern counterparts and could have only a dozen or two of stops, sometimes a single manual and, occasionally, no pedal; much like many Italian instruments.The music of south German composers on the whole concentrates more on melody, harmonic clarity and sound; genre-wise, Italian models were adopted and resulted in German versions of the toccata, a special brand of improvisatory preludes, and ostinato variation forms
