The chair of Mr. Bob is a 10 note JI scale created by [[DotuXil]]. The scale was designed to look like a chair in the [[Scale Workshop]] lattice visualization.
A chair scale is a JI or rank-4 scale whose lattice resembles a chair. It is used to refer to any lattice which is shaped like a chair, but formally, the lattice takes the form of a 2x2 cube, with an edge extended along the plane of one of its adjacent faces to another 2 notes, for a total of 10 notes in the scale.
[[File:Mr bob.png|thumb|The lattice for the Chair of Mr. Bob.]]
A formal chair can be identified, up to different modes of the scale, by its lattice subgroup (conventionally 2.3.5.7), the edge which is extended (out of 12), and which plane it is extended along (out of 2). Thus, for a given subgroup or other rank-4 tuning, there are 24 chair scales.
