How to put Left hand notes on the treble clef

Question

I want to put a note to be played by the left hand on the treble clef - using LilyPond.

How can this be done?

What I want to achieve is like this:

This is how my code looks right now:

Right Hand:

\repeat volta 2 {
    \time 4/4 
    <<c1-1 e1-3>> |<<c1 e1>> |<<c1 e1>> | <<c1 e1>>
}

Left Hand:

 \repeat volta 2 {
    r4 g'4-._2 g,2 | r4 g'4-.  g,2 | r4 g'4-. g,4 g4 | r1
}

This is giving me something like this:

Answer 1

What you are looking for is \change Staff. (See Changing staff manually)

Basically you just tell LilyPond to \change Staff and give the name of the staff you want to change to, but first you need to give the staves names (such as "up" and "down").

You should get something like this:

Code:

\new PianoStaff <<
    \new Staff = "up" {
        \time 4/4 \numericTimeSignature
        \repeat volta 2 {
            <c' e'>1-1-3 |
            \repeat unfold 3 {
                <c' e'>1 |
            }
        }
    }
    \new Staff = "down" {
        \time 4/4 \numericTimeSignature
        \clef bass
            \repeat volta 2 {
                \stemDown
                \showStaffSwitch
                r4 
                    \change Staff = "up"
                    g'4-._2_\markup{\italic"L.H."}
                    \change Staff = "down"  
                    g2_5 | 
                \hideStaffSwitch
                r4 
                    \change Staff = "up"
                    g'4-.
                    \change Staff = "down"  
                    g2 | 
                r4 
                    \change Staff = "up"
                    g'4-.
                    \change Staff = "down"
                    g4 g4 | 
                \stemNeutral
                R1 |
            }
    }

Notes:

• As well as writing "L.H." I used \showStaffSwitch which draws lines showing that where the voice in moving across staves. And turned this off (after it is clear what is going on) with \hideStaffSwitch.

• I used \stemDown to get the left hand note stems in the treble clef to go down. After the staff changes I used \stemNeutral to get them going in the default direction once more.

• I've simplified your chord notation, (you only need a single pair of chevrons < > for a chord).

• I also collapsed the repeated chords in the right hand (with a \repeat unfold), to save typing.

• I've used absolute note names (rather than relative note names), because they make much more sense to me, but this is not necessary at all.

• I used R1 instead of r1 for a full bar rest, so that it is centred in the bar.

• Maybe you want the automatic version \autoChange (documentation can be found the same page of the link above).
