Students will code a song in EarSketch that is a minimum of 20 seconds but less than 2 minutes. The songs must include at least one stem from Ciara or Common and contain one for-loop to include repetition as a musical element in their song. Repetition draws in the listener, making them a part of the song. Ciara's song "Set" has some great examples of repetition both in lyrics and beats. A for-loop tells the computer to execute a section of code repeatedly, a common notation in most programming languages. We can use for-loops to avoid repeated lines or sections of code, increasing for-loops in Python consist of three basic parts: the loop counter, the range, and the loop body. In order for the code to be part of the loop, it must be indented in the loop body. Students can loop fitMedia(), makeBeat(), or setEffect() functions in their for-loop. For-loops are especially effective in looping a background beat or drum beat to the whole song with only a few lines of code. Chapter 12 of the student curriculum will explain this concept in more detail. In addition to the for-loop, students should include functions such as fitMedia(), setEffect() , and makeBeat() to remix the additional sound clips.
