L.L. Heinrich Isaac - Innsbruck, Ich Muss dich Lassen

Heinrich Isaac lived from 1450-1517, and his life and body of work spread across the Early and High Renaissance. A very important German composer, and the teacher of Ludwig Senfl.

This piece, if I had to take my guess, is from the stylistically Early Renaissance output of Isaac. It is unaccompanied. Very little trace of counterpoint exist, and it still maintains a clearly modal sense of harmony. The line is very consistent and flowing, with rests indicating the breath in between the music and text. Each cadence hosts either an upper neighbor or an escape tone to indicate its approach. Very little dissonance is heard.
