The functionality of a diverse range of mobile applications for music composition is discussed in
this paper. The focus is on generic functionality requirements, the needs of novice and expert
users to compose music and some of the mobile applications for music composition available
from the iTunes App Store. The paper further addresses the gap that exists in current literature
about the functionalities required of mobile applications for music composition. In order to assist
composers of music (from novices to experts) to identify and choose the most appropriate
application for composing music on a mobile device, a framework is developed against which the
functionality of ten mobile applications for music composition is evaluated.
