I reset you example using this format.

The guitar part is two part counterpoint in which I would like to control where the steps go up or down. (1) In the guitar part, even though I have \voiceOne marked with \stemUp and \voiceTwo marked with \stemDown, why do the stems go down in both voices? (2) Is this snippet considered an example of "best practice", or how might others structure a file for such a group of instruments? Thank you for your help. \version "2.16.0" \include "english.ly" \score { << \new Staff = "voice" { \clef "treble" \time 3/4 \stemDown c''2 c''4 d''2 e''4 e''8 d''8 c''8 b'4 a'8 b'2 r4 } \new Staff = "guitar" { \clef "treble_8" \time 3/4 << \voiceOne { \stemUp c'2 c'4 b2 a4 c'8 d'8 e'4 f'4 e'4 d'2 } \voiceTwo { \stemDown c2 c4 g2 c'4 r4 g'4 d'4 g'4. fs'4. } >> } >> } % score I think it's better to use named voices. And in single staff polyphony, the stem direction is taken care of by the voices without having to explicitly set it - voiceOne and voiceThree default to stemUp, voiceTwo and voiceFour to stemDown. \version "2.16.0" \include "english.ly" vocal = { c''2 c''4 | d''2 e''4 | e''8 d''8 c''8 b'4 a'8 | b'2 r4 | } guitarUpper = { c'2 c'4 | b2 a4 | c'8 d'8 e'4 f'4 | e'4 d'2 } guitarLower = { c2 c4 | g2 c'4 | r4 g'4 d'4 | g'4. fs'4. } \score { << \new Staff = "voice" { \clef "treble" \time 3/4 \new Voice { \stemDown \vocal } } \new Staff = "guitar" { \clef "treble_8" \time 3/4 << \new Voice { \voiceOne \guitarUpper } \new Voice { \voiceTwo \guitarLower } >> } >> } % score |
