Disquiet Junto Project 0062: Life of Sine

The Assignment: Make music using just three sine waves.


Each Thursday at the Disquiet Junto group on Soundcloud.com a new compositional challenge is set before the group’s members, who then have just over four days to upload a track in response to the assignment. Membership in the Junto is open: just join and participate.

This assignment was made in the mid-afternoon, California time, on Thursday, February 28, with 11:59pm on the following Monday, March 11, 2013, as the deadline.

These are the instructions that went out to the group’s email list (at tinyletter.com/disquiet-junto):

Disquiet Junto Project 0062: Life of Sine

This week’s project involves making music from the basic building block of sound: the sine wave.

You will compose and record a piece of music using just three different sine waves, and nothing else — well, nothing else in terms of source material, but the waves can, after the piece has gotten underway, be transformed by any means you choose.

These are the steps:

Step 1: Devise which three sine waves you will employ. They should be different from each other in some evident way.

Step 2: The track should open with just one of the sine waves.

Step 3: Add the second sine wave at 5 seconds.

Step 4: Add the third sine wave at 10 seconds.

Step 4: Only at 15 seconds should you begin to in any way manipulate any of the source waves.

Deadline: Monday, March 11, 2013, at 11:59pm wherever you are.

Length: Your finished work should be between 1 and 4 minutes in length.

Information: Please when posting your track on SoundCloud, include a description of your process in planning, composing, and recording it. This description is an essential element of the communicative process inherent in the Disquiet Junto.

Title/Tag: When adding your track to the Disquiet Junto group on Soundcloud.com, please include the term “disquiet0062-lifeofsine”in the title of your track, and as a tag for your track.

Download: Consider setting your track in a manner that allows for attributed, commerce-free remixing (i.e., a Creative Commons license permitting non-commercial sharing with attribution).

Linking: When posting the track, be sure to include this information:
