Composition has been conceptualized as a method for communicating a way of thinking (i.e., cognition) from composers to performers and audience members. Music notation, or how music is represented in a visual format, becomes the vehicle through which such cognition is communicated. In the past, research on notation has been approached either categorically or as a taxonomy, where it is placed into separate categories based primarily on visual elements, including its symbols, conventions, and practices. The modern application of notation in Western classical music repertoire, however, has shown that the boundaries between these systems are not always clear and sometimes blend together. Viewing music notation from a spectrum-based approach instead provides a better understanding of notation through its cognitive effects. These spectra can then be viewed through multiple dimensions, all addressing different aspects. The first dimension consists of the historical systems of notation, ranging from standard music notation (SMN) to music graphics. Additional kinds of notation, such as proportional, pictorial, and aleatoric, work as the mediary levels between these two. The second dimension focuses on whether notation is processed intuitively, based on either cultural priming or general cognitive principles, or through conscious interpretation. The last dimension views notation as either …
