Editing Combining a time signature glyph and a default time signature

In mensural notation, you can find double time signatures, such as mensural 6/4 followed by the classical time signature 3/2 (in ternary white notation for instance). This scheme function, adapted from the http://lsr.di.unimi.it/LSR/Item?id=192 snippet, allows you to do so.

The glyph argument is the name of the glyph in the Feta font. This means that in fact this function can include any glyph. The baseline-skip value can be adjusted to your needs, as well as the font-size specifications.

                           (#:fontsize -1 #:column (a b)))))))
