For chordal accompaniment and singers performing in different keys, a touch-sensitive keyboard with transposition may be enough. Just check that its range suits the parts you need to play. If you need a written-out piano part with a wider range or a piano-style touch, compare 76-key models with an 88-key instrument. Also think about how the singers will hear you: built-in speakers, a headphone output and separate audio outputs do not necessarily serve the same purpose.
Who is this guide for?
Accompanists working with singers in different keys
If you play parts for different singers, look at the transposition options and how easy they are to use during a rehearsal. Yamaha specifies a transposition range of −12 to +12 semitones for the PSR-EW320.
Pianists playing written-out musical theatre parts
For two-handed parts, range and key action may matter more than automatic accompaniment. Yamaha specifies an 88-key GHC keyboard for the P-145; Roland lists an 88-key PHA-4 Standard keyboard for the FP-30X.
Accompanists in a shared studio
If you need to set the instrument up each time or let the group hear you, its dimensions, power supply and connections to the available sound equipment are all important considerations.

What to look for |
Who is this important for? |
| Key and accompaniment |
Check the transposition function and how it works on the exact model. Compare the keyboard’s range with your part; accompaniment styles are no substitute for a written-out piano part. |
If I accompany singers in different keys, I want to transpose quickly and have enough keys for my parts. Around 29% of consumers prioritise key and chordal accompaniment. |
| Range and piano-style touch |
Compare the lowest and highest notes in your part with the keyboard’s range. Also check how the exact model describes its key action. |
If I play a written-out piano part, I want the range and touch to suit it. Around 29% of consumers give range and piano-style touch top priority. |
| Setup, transport and power |
Measure the available space and allow for sheet music and cables. Check the weight, power options and what is included with the instrument. |
If I need to move or store the instrument after rehearsals, I want it to fit the available space and be practical to power. Around 21% of consumers prioritise setup space and transport. |
| Being heard and connections |
Ask what speakers or other equipment are available in the studio. Check that the connection you need matches the output on the exact instrument. |
If the whole group needs to hear the accompaniment, I want to know how the instrument can connect to the studio setup. Around 21% of consumers prioritise being heard by the group and having the right connections. |
Buying pitfalls when choosing a keyboard for rehearsals
-
Confusing touch sensitivity with weighted piano action
Descriptions of key action vary between models. Korg lists touch-sensitive LS keys for the Liano; Yamaha specifies a GHC keyboard for the P-145.
If piano-style touch is essential, compare the action on the exact models and try them out for yourself where possible.
-
Assuming a headphone socket provides sound for the group
Using headphones as the pianist does not automatically let the singers hear you. The Korg Liano has a combined headphone/line-out connection; Roland lists separate outputs for external powered speakers on the FP-30X.
First decide how the group will listen, then compare the instrument’s output with the equipment in the studio.
Depending on the equipment available, you may need suitable cables or external powered speakers.
-
Looking only at the number of keys
A wider range alone does not tell you about the touch, transport or space the instrument takes up. The models mentioned have different types of keyboard and stated dimensions.
Compare the range of your part with the key action, dimensions, weight and what is included in the offer.
Brands to compare for musical theatre rehearsals
Yamaha
Yamaha offers different options in the models mentioned: compact accompaniment, 76 keys or an 88-key instrument.
- Yamaha specifies 61 touch-sensitive keys and accompaniment styles for the PSR-E383; the brand lists 76 keys and transposition for the PSR-EW320.
- The PSR-E383 does not have the 88-key range of the P-145. Yamaha describes the P-145 keyboard as GHC.
Casio
Casio offers both a 76-key model and a more compact keyboard option with automatic rhythm patterns.
- Casio lists 76 keys and 61 tones for the CT-S1-76BK; the CT-S400 has 200 rhythm patterns.
- Features of the CT-S400 do not automatically apply to the CT-S1-76BK. Compare the specifications of the exact model with your part and how you plan to use it.
Korg
The Liano is an 88-key option for anyone weighing up a full range against a low stated weight.
- Korg specifies 88 touch-sensitive LS keys, transposition and a weight of 6,0 kg without batteries and the music stand.
- The LS keys are not described as a weighted hammer action. Korg describes the connection as both a headphone output and line-out.
Roland
The FP-30X is a portable digital piano option with a full keyboard and connections for external powered speakers.
- Roland lists an 88-key PHA-4 Standard keyboard, built-in stereo speakers and separate outputs.
- Check that the connections and space required for the model you choose suit the studio setup.
Kawai
The ES120 is an 88-key option for piano parts and setups with separate audio outputs.
- Kawai’s own brochure describes a Responsive Hammer Compact keyboard, 88 keys and separate line outputs.
- The brochure confirms that these features are included; its descriptions of the playing feel and sound are manufacturer claims.

Frequently asked questions about keyboards for musical theatre rehearsals
How do I decide whether I need 61, 76 or 88 keys?
Compare a representative musical theatre part with the range of the exact instrument. Note the lowest and highest notes you need to play; the number of keys alone does not tell you whether the touch will suit your preferences.
Can the singers hear me if I’m wearing headphones?
Not through the headphones alone. Check whether you can use the built-in speakers or connect the instrument to suitable external powered speakers. Korg lists a combined headphone/line-out connection for the Liano; Roland lists separate outputs for the FP-30X.
What should I check when setting up the instrument and powering it?
Check the dimensions and power options for the exact model, and follow the supplied manual for safe use. Korg lists a mains adapter as included with the Liano; check separately what comes in the box with other offers.
What about the statutory guarantee on a keyboard in the Netherlands?
According to the Dutch government, there is no fixed statutory guarantee period in the Netherlands. If there is a problem with a product, contact the seller to find a solution.
What should I look for regarding product safety and CE marking in the Netherlands?
Electrical and electronic equipment sold in the Netherlands must comply with the applicable European product rules. The Dutch government refers to CE marking and an EU declaration of conformity where required; the rules that apply depend in part on the product and any wireless functions. CE marking alone says nothing about playing feel or sound.
