Drag and drop the rhythmic cells onto the grid to fill all 4 measures of 4/4. For full credit, use each cell at least once. The rhythmic cells are of varying length, so a cell can only be placed in locations in the measure where it will fit. Repeating some cells will likely be necessary and sound nice. Each cell has set pitches, so play back your melody often, and do not be afraid to make changes until the given pitches and rhythms sound good to you.
