This cool piece for graduation ceremonies is specifically geared for upper elementary and middle school students. It employs a unique combination of jazz and hip hop. It is written as a two-part, with the lower voices in the bass clef. This should be a comfortable range for your lower, changing, or changed voices. It can be sung an octave higher if you have no lower voices, essentially making the song unison. (from Music K-8, Vol. 7, No. 5)
