![]() ![]() That is, a full-size piano will have a certain amount of white keys and black keys. However, there is one more thing to mention here. Note that each note has a distance of one octave. Even though they both are called DO, but they sound different. It means the first severe DO will have some hertz, and a more acute will have some hertz. Each of these notes is associated with a specific hertz. These notes are repetitive towards the bass or treble. These musical notes are DO-RE-MI-FA-SOL-LA-SI or C-D-E-F-G-A-B (in English).įrom DO on the left to the DO on the right, there is a distance of one octave. It also constitutes a minor third spanning from A 0 to C 8. How Many Keys on a Piano?Īs mentioned, the modern, full-sized acoustic piano has 88 specific keys with seven octaves. The composers now can fully express themselves with 88 keys. It was Chopin and Liszt, who first created the 88 keys pianos with seven and a quarter octaves. That period was considered as the Beethovian period.Īfter a lot of replacement and evolution, the piano gradually reached its full-size. Later after, pianos used to have 72 keys with close to six octaves. Instrument producers like, Broadwood and Stein were determined to meet the demand of musical composers of that time. However, the instrument producer started to bring innovation in the old harpsichord. Though the piano was limited both in quality and sound, it could make both soft and loud sounds. But, the newly created piano had only 49 keys or a range of four octaves. That piano used to produce sounds by using a brand-new hammer mechanism. He revamped the old harpsichord and created the pianoforte. With the progress of music, the piano arrived, which was made by Bartolomeo Cristofori. The musicians of that time were limited to a short range of five octaves only. One of the most used among them was the harpsichord, which has only 60 keys. Instead, there were different types of keyboard instruments. That time, the modern piano did not exists. Let’s take a short trip back to the 17 th century and the era of Vivaldi, Handel, and Bach. So, it is essential to understand how many keys on a piano. ![]() As you can see, the keyboard plays a prominent role in a piano. Most people consider the piano as a “percussion instrument” because of its striking action. The sound ends when the performer releases the key. However, this vibration transmits through a bridge to the soundboard, and finally, it generates a sound. Then, the strings continue to vibrate at their corresponding resonant frequency. When the performer presses down the keys, it activates the hammers to strike the strings. The piano is played using a keyboard, which includes a row of keys or small levers. Thanks again for joining us here at Living Pianos.The strings are struck by padded, wooden hammers that have a corresponding key. ![]() Is 97 the most number of keys on a piano? Not by a long shot! The Australian piano manufacturer Stuart and Sons manufactures a piano with 102 keys! I have not had a chance to play one of these pianos but I would love to have the opportunity. And the extra notes are available if you are so inclined to add them to your music. When you depress the sustain pedal, the extra bass strings resonate adding richness to the tone. The existence of these extra keys and strings enhances the sound of the piano. So why would you even want these other keys if they don’t really serve a purpose for 99% of the music you encounter? There are some pieces composers have written that include those lower notes, but this is very rare. The Imperial Concert Grand Bosendorfer piano has 97 keys! On this particular piano the extra keys have the colors reversed – the black keys are white and the white keys are black so you can distinguish the extra keys from the standard 88 keys. However, there are pianos made today that have more than 88 keys! Harpsichords (the predecessor to the piano) had different numbers of keys – sometimes even two keyboards! Near the end of the 19th century, 85 keys became the defacto standard for most pianos.īy the end of the 1800’s the piano had settled on 88 keys as a standard and the vast majority of pianos produced today feature 88 keys. The earliest pianos had around 5 octave of keys (about 60 keys). The standard number of keys on a piano today is 88 but if you’re familiar with the history of the piano, you know that this standard developed over a long period of time. ![]()
