Heinrich Isaac was born around 1450, in Brabant, Flanders and died around 1517 in Florence, Italy. He spent most of his younger life in the Low Countries; he was there until 1484. He was then offered the patronage of the Medici family by Lorenzo de Medici. Not much is known about his education besides the fact that it primarily, if not only, took place near his home town. There is no doubt, however, that he got a grand education because the music schools during his life time were pristine. Isaac was a hard worker and was always looking for another job to do. He was happy to work for one family as long as they had power and a connection to the church. When the Medici fell he quickly left them and found a well-paying job. When the Medici regained power he begged for his position back. He composed many great motets, masses, and carnival pieces. The carnival pieces have all since been lost. His works took influence from his Flemish background and were written in French, German, and Italian. Of his works the most famous ones would be: Innsbruck, Ich Muss Dich Lassen, several pieces in the Proper of the Masses, and his largest, unfinished work, Choralis Constantinus. Isaac had mainly in the Classicism works and also Humanism.
The name of this piece is "Innsbruck, Ich Muss Dich Lassen. The timeline of the piece is unclear, it is said to be created around 1510. This piece is still sung in German churches, is often found on CD's, and several places on the internet. This piece has 4 different voices, Soprano, Alto, Tenor, and Bass. It has been translated into many different languages and texts. There is controversy about the piece, however, it is unclear who wrote the melody and whether or not the tune was stolen from another composer. The piece was eventually declared Issac's and is now considered his today by the majority of people. I find this piece so interesting because of all of the emotion that the music portrays. It is sad and depressing. The piece is about a journey a person must take and they must leave their home. They hope that they will not lose themselves in the process of leaving their 'land of perfect day' but they must go on their journey to find themselves. He does not want the homeland to forget him. This piece is an example of humanism, because Heinrich likes to play with the emotions of people and this piece make you feel melancholic for the narrator. You can feel the emotion of the narrator and how sad he is to leave his homeland. He is depressed and worried about not being able to find his way back. The slow tempo and soft dynamics add to the heartfelt melody.
