Humdrum Representation for Number of Active Voices¶
**vox# – representation of number of concurrently active voices
The **vox# representation permits the representation of the number of notes sounding together at successive moments in time. The **vox# representation distinguishes just two types of data tokens: number-tokens, and barlines. Each **vox# number-token consists of a single integer value indicating the total number of simultaneously sounding voices. Barlines are represented using the “common system” for barlines – see **barlines**.
It is recommended that files containing predominantly **vox# data should be given names with the distinguishing `.vox’ extension.
The following table summarizes the **vox# mappings of signifiers and signifieds.
0-9 integer values; measure numbers = barline; == double barline ; pause (for barlines)

The following Humdrum command produces **vox# data as output:
**vox** determine number of concurrently active voices for **cbr, **cents, **cocho, **deg, **degree, **freq, **kern, **pc, **pitch, **semits, **solfa, **solfg, **specC, and **Tonh
The following tandem interpretations can be used in conjunction with **vox#:
