I am trying to denote something where I play a chord, lets say C, but then then I keep playing the note e (for a whole note) key and stop on the other two notes (c and g). Then i play the g note (or c and g) again as a quarter note. Basically I want a whole note at c and then during that whole note i want quarter notes (e and g) played through that measure. I don't think this will effect the answer but the end of that measure's c note is a whole+1 note and the next measure is g quarter notes.
I am trying to engrave this with Lilypond, but just knowing the name of what this is will probably allow me to find it.
