How to Act While Playing an Instrument on Stage

You’re downstage with a guitar strapped on, and your scene partner has just said the thing that should land like a slap. Your face is supposed to change. Instead, part of your brain is counting the bars to the key change, and your left hand is hunting for a chord you only half know. The moment goes by, and you played it like someone waiting for the next song.

That split is the whole challenge of actor-musician work. In a show where the cast is also the band, the instrument is never just accompaniment. It’s part of the character, part of the staging, and often the thing the audience is watching. If your attention lives in your fingers, the scene stops.

The short version: get the music so deep in your hands that it no longer needs your attention, then rehearse it as the character, never as a separate gig. Learn your dialogue away from the instrument so that the words don’t compete with the notes. Practice cueing and listening to the rest of the company, because often there’s no conductor. And when you audition, prepare the acting and the playing as two strong, separate pieces, then show you can join them.

Know what the job asks for

Actor-musicians are actors first who also make the show’s music live on stage, often with no band in the pit. Director John Doyle told American Theatre that, working in UK regional theater, a limited budget with a 10-actor cap pushed him to find actors who could play instruments. He later brought the approach to Broadway with his production of Sondheim’s Sweeney Todd, and he says the form is now taught in drama schools around the world.

In the UK, it’s a degree subject in its own right. Rose Bruford College says its course was the first of its kind, and that you’ll need to play at least one instrument to a good standard. It adds that it doesn’t typically count voice as an instrument. Mountview’s course asks for a “high level of proficiency” on at least one instrument, though formal music qualifications aren’t essential.

In other words, singing well doesn’t make you an actor-musician. The instrument is the extra skill. The good news is that some directors build the show around it. Doyle told TheaterMania that a show’s instrumentation depends on who you audition and what they can play. Patti LuPone came to his Sweeney Todd with euphonium experience and ended up playing tuba.

Get the music into your hands before the scene needs you

You can’t act a moment while you’re still reading it, and the same is true of the notes. If you have to think about a fingering, that thought comes out of the scene. So the first job is to make your part automatic, the way a line you know cold comes out while you’re busy listening to your partner.

Professional rehearsal schedules assume you’ll get there fast. Michael Cerveris, who played Sweeney in Doyle’s Broadway production, told Playbill that the company rehearsed the music for each section the day before they staged it. Then they put music, blocking, and acting together at once and ran each section again and again. He called it “a huge amount of repetition.”

That company also played most of the score without sheet music on stage. Only the piano book stayed out. Francesca Loren, an actor-musician trained at Rose Bruford, told A Younger Theatre that on professional shows you have to work quickly, with no time for a slow process of learning arrangements. Her advice was simple: be as good as you can be on your instruments.

A few habits make the hands-first stage go faster:

• Learn your part from the first music call with the right notes and the right fingerings, because anything you practice wrong will come back on a tired night.
• Practice standing, walking, or sitting the way you’ll actually be staged, since a part that’s solid in a chair can fall apart when you’re moving.
• Run the tricky passages while you talk or look around the room, which tells you whether they’re truly automatic.
• Mark the moments where you start or stop playing in your script, so you know exactly where the music and the dialogue hand off.

Learn the words away from the instrument

Dialogue and music compete for the same attention, so don’t make them learn each other at the same time. Work on both in parallel but keep them apart: lines from your partner’s cues at home, music in the practice room, and combine them only when each is solid. When the words come without effort, you’ll have room in your head for the counting.

Test yourself from the cue rather than rereading. In Offbook, realistic voices read every other part and wait for your line, and you can hide your lines so you have to recall each one from the cue, or swap them for first-letter cues as a step on the way. If you’d rather start without an app, the free line memorizer turns any speech into first-letter cues, no account needed.

Pay special attention to the lines just before and just after you play. Those are the seams, and they’re easy places to go blank, because your brain is switching jobs. Our guide to learning lines for a musical has more on drilling the joins between scenes and songs.

Play it as the character, not as yourself

Here’s the shift that separates a good actor-musician from a good musician in costume: the character is the one playing. The Chance Theater, writing about its production of Once, puts it neatly. A character picks up an instrument because the character needs to, not because the show demands a song.

So ask the same questions you’d ask about any action. Why does this person start playing now? What do they want from the person they’re playing to? Are they showing off, hiding, comforting someone, or trying to drown out an argument? Cerveris described the job as telling the story with your fingers, and the answer changes how you play, not just how you look while playing.

Loren offered a useful way to think about it. She said the instrument is like costume: it can stop you moving freely, or it can force you into walking a particular way, and that can add a dimension to the character. A saxophone slung low, a fiddle tucked under the chin, or a cello you can’t walk away from each set limits on your body. Use them.

A few things change when you play in character:

1. Your tone and dynamics follow the character’s mood, inside what the musical director has set.
2. Your eyes go where the character’s attention goes, which is usually your scene partner, not your hands.
3. Your reactions keep going while you play. If someone says something shocking mid-song, the character hears it.
4. How you pick up and put down the instrument becomes an action, not a scene change.

Keep the scene alive while your hands are busy

Watch out for a frozen face. When you’re concentrating on playing, your expression can freeze into a musician’s focus, and you stop listening. The fix is the same as in any scene: put your attention on the other person and let your reactions happen.

That only works if the playing is secure enough to run without you watching it. If you catch yourself staring at your fretboard or keys in a scene, that’s a sign the passage needs more repetition in the practice room, not more willpower on stage.

Listening also matters musically. Doyle’s Sweeney Todd had no conductor. Cerveris told Playbill that when something needed a cue, the cast would sniff or lift their eyebrows, and that they had become good at playing as a unit. Doyle described the form to TheaterMania as “a troupe of people doing it together.”

That means your scene partner is also your bandmate. Learn their musical cues as carefully as you learn their lines. Know who starts each number, whose breath or nod you’re watching, and what you do if someone comes in early. The Chance Theater’s description of Once notes how performers adjust to each other from moment to moment, and that’s the habit to build in rehearsal.

Finally, rehearse the transitions with your hands full. A lot of physical trouble happens in the seconds between scenes: unhooking a strap, finding a chair, putting a violin down without a clunk during someone’s quiet line. Staging these early saves you from improvising them in tech.

Prepare an audition that shows both skills

Actor-musician auditions test both skills. Mountview’s first round, for example, tests the speeches and the playing separately and adds an improvisation exercise done in a group. Mountview’s 2025-26 audition handbook for its BA Actor Musicianship is a good example of what schools ask for. You can read the full handbook, but the main points are these:

• Two speeches: a contemporary prose monologue from a play written after 2000 and a verse speech, each no longer than two minutes, in your own accent, playing a character close to your own age.
• A recorded music submission: two contrasting instrumental pieces, four minutes combined at most, on one instrument or two, in any genre.
• The voice doesn’t count as an instrument, though you can add sung or spoken text to one piece as long as the focus stays on your playing.
• Your video should be framed head and shoulders, including your instrument and hands.
• A spontaneity and improvisation exercise on the day, along with your speeches.

Requirements change from year to year and from school to school, so always check the current page for the program you’re applying to. Professional actor-musician castings vary even more, so read each breakdown for exactly what it wants you to bring and play.

Whatever the format, a few choices help. Pick music that shows what you can play now, cleanly, rather than a piece at the edge of your ability; Mountview asks for pieces that reflect your current level. Make the two pieces genuinely contrasting in tempo and mood. Time your speeches with a monologue timer, because a two-minute limit is easy to break when you add a pause or two.

If you play more than one instrument, list them honestly with your real level. Directors like Doyle build the band from the people they cast, so a solid second instrument can matter more than you think. In any group part of an audition, treat the others as your band: listen, make room, and work together. Mountview’s course page quotes Peter Rowe, artistic director of the New Wolsey Theatre, calling strong acting plus strong music skills “absolute gold dust”.

Questions actors ask

How do actor-musicians act and play at the same time?

By making the music automatic first, so their attention is free for the scene. They learn their parts early and repeat them until they don’t need to watch their hands, learn their lines separately, and then rehearse the music, staging, and acting together. On stage, their focus goes to their scene partner, the same as in any scene.

What do actor-musician auditions ask for?

At drama schools, acting speeches, instrumental pieces, and often an exercise done in a group. Mountview’s 2025-26 handbook asks for a contemporary prose monologue, a verse speech, and two contrasting instrumental pieces on video. UK drama schools such as Rose Bruford and Mountview don’t usually count voice as your instrument. Professional castings vary, so read each breakdown closely.

Should I play my instrument in character?

Yes. In an actor-musician show, the character is the one playing, so the playing should come from what they want in the moment. Your tone, your focus, and how you handle the instrument all tell the story. Keep it inside the musical director’s choices, since the band still has to sound together.

What level do I need on my instrument?

Rose Bruford asks for at least one instrument to a good standard, and Mountview asks for a high level of proficiency, without requiring formal music qualifications. Professional shows can ask you to learn parts quickly; in Doyle’s Sweeney Todd, Michael Cerveris told Playbill, most of the cast played without sheet music.

Does singing count as an instrument for actor-musician work?

Not usually. Rose Bruford says it doesn’t typically count voice as an instrument, and Mountview’s audition handbook says the same for its music submission. Most actor-musicians do sing as well, so keep a song ready, but the instrument is what sets the work apart. If you’re mostly a singer, our guide to acting a song may be the better place to start.
