I think the only way to do this is to put them in the same \score, synchronised. I think LilyPond will even make an effort *not* to line things (e.g. barlines) up unless they are part of the same system to avoid visually misleading a reader into something like skipping a system. Here's what I mean by putting them in the same \score. I hope this helps: \score { << \omit Score.SystemStartBar \new Staff \relative c' { \once \override Staff.TimeSignature #'stencil = ##f \time 15/1 { \set stringNumberOrientations = #'(down) \set fingeringOrientations = #'(left) <e\4-2 g-0 c-1>1 <f-3 a-2 d-4>1 <g b e>1 <a\3-2 c-1 f-1>1 *1 <c-2 e-4 a-3>1 <d-2 f-1 b-3>1 <e-2 g-1 c-1>1 <d f b>1 <c e a>1 *1 1 <g b e\4>1 <f a d>1 <e g c>1 } } \new Staff \relative d' { \once \override Staff.TimeSignature #'stencil = ##f \time 15/1 \key d \major \relative d' { <fis a d>1 <g b e>1 1 *1 <cis e a>1 <d fis b>1 <e g cis>1 <fis a d>1 <e g cis>1 <d fis b>1 <cis e a>1 *1 1 <g b e>1 <fis a d>1 } } >> } Kevin
