How Many Black Keys Are On A Piano?

By Music Critic Staff· Last Updated: February 16, 2024

The number of black keys on a piano can vary. There are only 35 black keys on some pianos, while others have 37. However, the most common number of black keys on a piano is 36.

So why do pianos have a variety of black key counts? This instrument's past is what ultimately matters. Early in the 1700s, the first piano was created. Because it was a modern piano, black keys were more prevalent compared to white piano keys back then. The piano makers changed the design of those in the future, eliminating the extra black keys.

Today, in all the keys, we mainly use the 36 black keys for playing chords and melodies in piano music. Many popular songs can be played using just the white keys on a piano. If you want to try it out, here's a simple song that uses only the C major scale: "Twinkle Twinkle Little Star."

But that doesn't mean that the black keys are unimportant or don't affect how you play music. They are essential in creating different sounds, especially in western music and harmonic combinations. So next time you're playing your favorite song on the piano, don't forget to use those black keys too!

Why the Number of Black Keys Can Vary

The number of black keys on a piano can vary because pianos are manufactured in different ways. Some manufacturers put more black keys on a piano than others. For example, some manufacturers might put two black keys next to each other to make it easier for pianists to play certain chords. Other manufacturers might put only one black key between two white keys because they think it looks better aesthetically. However, the most common number of black keys is 36.

Types of Pianos

The number of black keys on a piano can vary depending on the make and model of the instrument. Most pianos have 36 black keys, but some have fewer or more. If you're trying to learn a particular song or scale that requires you to play a black key, it's essential to know whether your piano or keyboard instrument has that key. Additionally, knowing how many black, sharp, and flat keys are on your piano can help you understand which notes you're playing when reading sheet music and discover extra keys. Here's a breakdown of how many black keys are on different types of pianos.

Acoustic Pianos

Most acoustic pianos—uprights and grand ones—have 36 black keys, equivalent to 88 keys total. This includes all standard concert grand pianos, Baby Grands, Upright Pianos, Spinets, and Console Pianos. There are a few exceptions to this rule. Some tiny upright pianos and spinets may have only 34 black keys, while some larger 7-foot grand pianos can have as many as 38 black keys.

Digital Pianos

Digital pianos typically come in two varieties: those with weighted keys and those with unweighted keys. Weighted keys are designed to mimic the feel of an acoustic piano, while unweighted keys are more commonly found on portable keyboards and synthesizers. The type of digital piano you have will determine how many black keys it has.

Weighted-Key Digital Pianos Generally Have 36 Black Keys

Weighted-key digital pianos are designed to replicate the feel and sound of an acoustic piano as closely as possible. As such, they typically have the duplicate black keys as an acoustic piano—36—which equals 88 total keys. There are a few exceptions; some small digital pianos may have 34 black keys instead of 36.

Some companies, such as piano manufacturer Steinway, also make 88-key digital pianos with weighted keys that don't necessarily imitate the feel of an acoustic piano—these may have additional features like built-in speakers or USB connectivity that add weight and bulk to the keyboard itself, resulting in fewer than 36 black keys.

Unweighted-Key Digital Pianos Vary Greatly in Size and Number of Keys

Unweighted-key digital pianos come in all shapes and sizes, from compact 25-key controllers to full-size 88-key synthesizers. As such, this instrument has no set number of black keys; it varies greatly depending on the make and model. That said, most unweighted-key digital keyboards have between 61 and 76 keys, which means they usually have between 30 and 38 black keys—fewer than the average acoustic or weighted-key digital piano.

Final Key

In conclusion, the number of black keys on a piano can vary depending on the make and model of the instrument. Most pianos have 36 black keys, but some have fewer or more. If you're trying to learn a particular song or scale that requires you to play a black key, it's essential to know whether your piano has that key.

Additionally, knowing how many black keys are on your piano can help you understand which notes you're playing when reading sheet music. By understanding how many black keys are on your specific make and model of piano, you can better equip yourself to become a master musician!
