Ivan: When I write polyphony for the piano I use << { %here pitches for top voice } \\ { %here pitches for bottom voice} >>. Lilypond seems to take care of the stem directions.
I reset you example using this format. Some notes of the voices might need to be adjusted. \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 <<{ c'2 c'4 | b2 a4 | c'8 d'8 e'4 f'4 | e'4 d'2 } \\ { c2 c4 | g2 c'4 | r4 g'4 d'4 | g'4. fs'4.} >> } >> } % score Mark -----Original Message----- From: lilypond-user-bounces+carsonmark=ca.rr....@gnu.org [mailto:lilypond-user-bounces+carsonmark=ca.rr....@gnu.org] On Behalf Of ivan.k.kuznet...@gmail.com Sent: Friday, March 15, 2013 8:52 PM To: lilypond-user@gnu.org Subject: stem directions in music for voice and guitar Attached is the beginning of an arrangement for voice and guitar. 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 _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
