cuicani (Mdz43r)

The symbols inside the segments are reminiscent of symbols for writing or painting, as shown on folio 70 recto, where a "pintor" writes on a codex. See Mexicolore for this an another image (of a woman) writing/painting. The outside of the scroll of this glyph for cuicani has small, white, curling shapes that could be feathers. The elaborate decorations on the speech scroll may take speaking to a new height to represent singing.

Scrolls associated with representations of sounds can also be found coming out of drums. See, for example, Valeria Ballomia, "Sound artefacts as containers. The materiality of rhythm in ancient Mesoamerica," Pallas: Revue d'Études Antiques 15 (2021), 121–145, especially section 4.

Other symbols inside the large scroll here may include shells, including the turbinate shell that appears so often splashing off from a stream of water. See the examples of the shells called cilin and cuechtli, below. Jeanette Peterson (The Paradise Garden Murals of Malinalco, 1993, 47) identifies a song scroll in the Malinalco murals, and in it she identifies the ilhuitl sign (which also stands for writing and the tonalamatl), the shell, and a flower. So, in content, it is very similar to this glyph.
