Layout terminology: Grand staff and tablature
I see that layout property organization and terminology is now markedly improved in MuseScore 3.6.
However a property entitled "Grand Staff Distance" governs the spacing between a "regular" notation staff and tablature, for instance, 8vb treble clef and a linked tablature staff.
But I'm not sure if a treble clef and a linked tablature staff can correctly be considered to be a grand staff.
I think of them as staves within a system/track, and accordingly the distance between them would be governed by "Staff distance."
I think of a grand staff as a bracketed pair of staves that affords a widened range of pitch for an instrument like piano, harp or organ. However the term grand staff can also it can pertain to any bracketed pair.
Am I incorrect in this opinion?
Then in MuseScore we see that Guitar + Tab template produces an unbracketed pair, where the tablature staff does not extend the range of pitch for an instrument, but merely duplicates the notation in a graphical representation of a particular stringed instrument in a particular tuning.
