The pitch set represents every Hampartsum pitch sign used in the piece and its transcribed value in staff notation. This means that the original Hampartsum pitch signs from the source are shown as their equivalent in staff notation based on the editor’s choices, making the pitch set concept more visible. 

In CMO critical editions, editors can follow and utilize theoretical approaches that most accurately reflect the pitch understanding of the manuscript they are working on. For example, in early manuscripts, pitch signs that are modified with various additions, such as tildes or strokes to distinguish and detail different pitches, may not be adequately conveyed by the AEU (Arel-Ezgi-Uzdilek) system prevalent in the 20th century. Consequently, some editors might turn to different pitch systems and represent these pitches based on those theoretical frameworks. This demonstrates the receptiveness of CMO editions to new and/or different theoretical approaches, allowing flexibility for the editors rather than adhering to a single theoretical framework.

Steps:

Compile a list of All Pitches 

• List all pitches used in the piece

• Create a new Sibelius file for the pitch set (use “Pitch set template.sib”).

Enter Total Number of Pitches

• Enter the total number of pitches as the measure of the pitch set

Copy-paste Hampartsum Signs

• Enter all used pitches in staff notation with stemless noteheads. The notes can be copied from “Pitches.sib” and placed inside one measure with the beat number hidden.

• Copy-paste the relevant Hampartsum signs under every note of the entered staff notes from “Symbols for pitch set”.

Export the Pitch Set

• Export the pitch set from Sibelius as TIFF file.

• Import the TIFF file into the Critical Report
