He is considered by many to have been the greatest Spanish Baroque composer, and has been called the Spanish Bach.
According to the title this Tiento should be played on a divided manual.
The accompaniment is in the lower half of the manual and the melody is played on the Cornet in the descant, devided on the central c.

Adam of Fulda (c.1445-1505)
