Tips for Choosing the Number of Piano Keys
1. Establish Your Goals
Where do you intend to play the piano? And are you a beginner or a professional player? Have you got plans to play professionally, or you just want to play it as a hobby?
If you plan to learn first and then pursue a career as a professional pianist, you may want to try the baby grand first. It may seem difficult, but if this is your goal, you have to get used to playing the full 88 keys.
In cases when you merely wanted to learn as a hobby, you could pick a digital or a petit piano with fewer keys (61, 66, or 72.) With fewer keys to remember, you can quickly learn to play.
Furthermore, if the piano is for your children, you can opt for the keyboard with 44 keys.
2. Select the Correct Keyboard
In case you want to use a keyboard, pick a keyboard with 88 keys and 7 octaves. There are keyboards with only 54 notes. Ensure that it has weighted keys too.
The weighted keys will make it easier for you to play the traditional piano keys later on. An adjustable stand is essential to position the keyboard properly.
3. The Sufficient Number of Piano Keys for Beginners is 66
How many keys should a piano have for beginners? The piano should have 66 keys for beginners to learn sufficiently. The 66 keys are enough for you to learn how to play.
4. The Number of Piano Keys Is Proportional to Its Playing Power
The more keys you have, the more notes you can play. So the number of keys is directly proportional to the piano’s playing power.
Naturally, this applies only when you are a professional pianist. Numerous keys can be daunting for beginners.
5. Consider the Keys’ Durability
Do not only consider the number of keys, but you should also consider the keys’ durability. Choose ivory over plastic piano keys as they are more durable. Ivory keys also absorb sweat from the fingers, making it easier to play.
Nonetheless, many piano makers are now using white plastic rather than ivory due to ethical reasons. There is a global ban on the use of ivory as it comes from elephant tusks.
You can choose well-known brands to ensure that your white plastic keys are long-lasting. Examples are Yamaha and Steinway.
