> Are the letters used in "Roman numeral harmonic analysis" Roman
> numerals or are some other letters also used ?
There are quite a number of different systems out there, but it's common to them all
that they use some combination of Roman letters with numbers (often subscript or
superscript), musical accidentals (flat / sharp signs); plus / minus / greater-than or
smaller-than signs, and other graphical symbols such as strokes, brackets, circumflex
accents...
Many systems (including the "Schenkerian" analysis that is fashionable in the
Anglo-Saxon world) use capital Roman numerals as their base symbols while other
systems (such as the "Riemannian" analysis that is common in Germany) use letter
combinations that stand for the harmonic functions: T, D, S, Tp, and so forth,
including the "double-dominant" and "double-subdominant" symbols (partial overlay of
two "D"s or two "S"s respectively.)
