how to enter 6 notes with four of them forming two pairs in guitar

[Sherry C]

Hi Alex,

From a purely technical standpoint in using Notation Composer (and a professed ignorance for guitar sheet music convention), if you want to enter all those notes on one staff at the same time point, you'd need to have the "duplicate" note pitches entered in two voices (to read more about voices, see Help/Users Guide, and use the Index to look up "voice").

So, for instance, you could enter the first three strings' notes using Upper Voice, and the last three strings' notes using lower. This will give the two duplicate note pitches (B and G) two stems, up and down.

Is this what you're looking for?

ttfn,
Sherry
