Casio vs Yamaha for beginner keyboards

Almost every beginner keyboard sold is made by one of these two companies, which is why the comparison comes up constantly and why most answers to it are useless. They are not far apart on quality. They are quite far apart on philosophy.

Both picks state their Starter Path band, and we have not physically tested any of them.

The models that actually compete

At the 61-key tier it is the Yamaha PSR-E383#ad against the Casio Casiotone CT-S1#ad, with the Casio Casiotone CT-S200#ad sitting a step below as the children’s option. At the weighted 88-key tier Yamaha’s Yamaha P-145#ad is the instrument everything else gets compared against.

Sounds: 650 against 61

The PSR-E383 carries 650 tones. The CT-S1 carries 61 and a deliberately uncluttered panel.

On paper that is a rout. In a practice room it is not, and this is the single most useful thing on this page: an instrument with 650 sounds gets browsed, and an instrument with a piano sound and a volume knob gets played. Casio chose the second thing on purpose, and for an adult beginner it is frequently the better instrument because of it.

For a seven-year-old the calculation reverses. The novelty of 650 sounds is why the instrument keeps getting switched on at all, and a child sitting down voluntarily is worth more than a child practicing efficiently.

Polyphony: 64 against 48

The CT-S1 has 64-note polyphony. The PSR-E383 has 48. Polyphony is the number of notes the instrument can sound at once, including notes still ringing under a sustain pedal, and when you exceed it the oldest notes are cut off.

Forty-eight is enough for a beginner and it is the lower number. If the player holds the sustain through a dense passage, the Casio holds together for longer. This is a real, checkable advantage and it is rarely mentioned.

For comparison, the weighted P-145 also has 64, and the Alesis Recital has 128. What that number means in practice is explained in keyboard specs explained.

Lessons: Yamaha wins clearly

The PSR-E383 has 125 lesson songs with right-hand, left-hand and both-hand practice and an evaluation score at the end. It is not a gimmick; hand-separate practice is how piano is actually taught, and having the instrument enforce it is genuinely useful for a child working without a teacher between lessons.

The CT-S1 has none of this, by design. If the buyer is a parent hoping the instrument will carry some of the teaching load, that decides it.

What built-in lessons can and cannot replace is covered in piano lessons versus learning apps.

Size and weight

The CT-S1 is 9.9 pounds and 3.3 inches tall. That is genuinely shelf-sized, and an instrument that can be put away and brought out again in ten seconds gets used in houses where a permanent setup is not possible.

Both brands include a power supply with the models above, which is worth confirming because plenty of portable keyboards at this tier do not, and one without its adapter is furniture.

The thing neither of them solves

Both are 61-key, unweighted instruments. Neither will build the finger strength an acoustic piano demands, and neither has the range a method book eventually assumes.

If formal piano lessons are already scheduled, the brand question is the wrong question. Buy 88 weighted keys. Yamaha’s Yamaha P-145#ad is where that tier begins: graded hammer action across all 88, a concert grand sample and 24 pounds. The full argument is in 61 versus 88 keys.

Where each range goes next

Worth knowing before you buy, because the step-up path is part of what you are choosing.

Yamaha has the clearer ladder. The PSR line continues upward with more keys, better speakers and more arranger capability, and the separate P series runs from the P-145 up through progressively better hammer actions. A family that starts on a PSR-E383 and moves to a P-series piano is following a path Yamaha has deliberately built, and the controls stay familiar the whole way.

Casio splits rather than climbs. Above the Casiotone line sits the Privia range of weighted digital pianos, which is a genuinely different instrument rather than a bigger version of the same one. That is not a criticism — it reflects Casio’s view that a portable keyboard and a digital piano are two products for two jobs, which is a defensible position and the same one we take in keyboard versus digital piano.

The practical consequence: if you expect to upgrade inside two years, Yamaha’s continuity is worth something. If you expect this keyboard to be the only one for a long time, buy whichever instrument suits the player now and ignore the ladder entirely.

What is actually in the box

Both the PSR-E383 and the Casiotone models above include a power adapter and a music rest, which is worth confirming rather than assuming: plenty of portable keyboards at this tier ship without a power supply, and a keyboard without one is furniture until a second purchase arrives.

Neither includes a stand, a bench, a sustain pedal or headphones, and a beginner wants at least the first two and usually all four. That gap is the same on both brands, so it does not decide the comparison, but it does decide the budget. Sizing and heights are in keyboard stand and bench guide, and the complete list is in keyboard accessories you actually need.

How we would decide

Child, no teacher yet: Yamaha PSR-E383, for the lesson mode and the touch response.

Young child, first instrument: Casio CT-S200 — full-size keys at a price where mini keys are the norm, and a power supply in the box. Detail in best keyboards for kids.

Adult beginner, self-taught: Casio CT-S1, because fewer features means more practice and the polyphony is better.

Anyone with lessons booked: neither. Skip to best beginner digital pianos.
