# Lilypond: How to write - when the left hand should play more than the number of notes per bar as per the time signature

This is what I am aiming for:

How can I tell LilyPond that the `c1` in the first three measures is to be played by the thumb of the left hand in parallel with the other three notes also played by the left hand?

``````   r4 a4_3 a4 a4 |
r4 g4_4 g4 g4 |
r4 f4_5 f4 f4 |
c'2_1 c,2
``````

Where do I put in those `c1` notes?

A polyphonic passage can be coded in a number of different ways (see the documentation here).

For this case, I'd suggest writing it like this:

``````<< {c1^1} \\ {r4 a4_3 a4 a4}>> |
<< {c1} \\ {r4 g4_4 g4 g4}>> |
<< {c1} \\ {r4 f,4_5 f4 f4}>> |
c'2 c,2
``````
• Thanks a lot - this works fine! But there are a couple of warnings warning: maybe input should specify polyphonic voices warning: cannot have note heads and rests together on a stem ... For the sake of completeness - could you also please give the other way of adding this polyphony? Dec 3 '21 at 11:30
• @saraf — That's strange, I'm not getting any warning. What version of LilyPond are you using? And what does the rest of your code look like? Dec 3 '21 at 11:38
• Yup! That did the trick :-) Tnx Dec 3 '21 at 12:36
• as I understand it, the double backslashes make both voices temporary, rather than just the second voice. But different versions handle them differently for some reason Dec 3 '21 at 12:43
• @saraf Using << A \\ B \\ C ... >> implicitely creates new voices for each bit and applies voiceOne, voiceTwo, ... to them. So << c1 \\ { r4 a a a } >> is equivalent to << \new Voice { \voiceOne c1 } \new Voice { \voiceTwo r4 a a a } >>. As this question is a bit basic I suggest you read this part of the documentation to get a principle understanding of how polyphony works in Lilypond: lilypond.org/doc/v2.23/Documentation/notation/multiple-voices
