Fact #1: The Piano was Invented in the 1700s

The birth of piano and piano music is dated back to the 1700s. It was the brainchild of Bartolomeo Cristofori, an Italian harpsichord maker. Harpsichord is an ancient musical instrument focused on plucking strings to create sound rather than hammering.

He sought to create a keyboard instrument with soft and loud tones, something his predecessor couldn’t do. Eventually, he created the modern piano (formerly called pianofortes).

Fact #2: The First Musical Composition Specifically Created For Piano in 1732

The piano is a versatile and quality instrument that can play various musical compositions from different genres. Lodovico Giustini did the first piece of music specifically composed for the piano in 1732. This musical piece is known as “Sonate da cimbalo di piano e forte detto volgarmente di martelletti” and combines a harpsichord and piano-like sound.

Fact #3: The Design Of The Modern Piano Hasn’t Changed Much

Although the first pianos were very different from those we have today, the design has been tweaked and perfected over time. Since then, there have been a few minor changes, such as varying the length of strings for some notes or adding pedals to increase their range of sound. Overall, the modern piano’s design hasn’t changed much for over 250 years.

Fact #4: The Grand Piano is the Biggest Piano Model

Most of us are well acquainted with the regular-sized acoustic piano, but did you know there are other sizes as well? The grand piano is the biggest and most expensive type of piano. They can be 6 to 9 feet long and cost up to $100,000. But what makes them so pricey?

Grand pianos are made with intricate parts and feature a longer soundboard. It means better sound quality, making them the most sought-after by professional musicians.

Fact #5: David Klavins is the World’s Largest Piano Maker

The Klavins M450i is the largest piano in the world and was designed by David Klavins. The massive creation measures 15 feet tall. This acoustic piano is so massive that it requires climbing up a staircase to access the keyboard. Every inch of this piano is handcrafted with precision, from the soundboard to the action. The M450i looks beautiful, yet its size makes it extremely challenging to move and install in any room.

Fact #6: Steingraeber & Söhne Still Provide Handcrafted Piano Today

Steingraeber & Söhne is a German piano company established in 1852 and remains one of the oldest companies making handcrafted pianos. Their instruments are highly sought after for their quality craftsmanship and rich, vibrant tones. Each piano is crafted from the finest materials to produce high-quality sound over time.

Fact #7: There are 88 Keys in an Acoustic Piano

Originally the piano had 54 keys when it was created. Still, with improvement in music and tones, the full range of an acoustic piano comprises 88 keys. It includes seven octaves plus three additional notes. Each note has its unique sound and can be played with other notes to create beautiful melodies.

Fact #8: Pianos Require Regular Tuning

One of the essential elements of owning an authentic piano is regular tuning. The strings inside the piano stretch and shrink due to temperature changes and progress in playing skills. It is essential to get a piano serviced or tuned twice each year.

Fact #9: Learning Piano Improves Memory

Learning how to play the piano requires memorization of notes and chords. It helps build strong memory skills and develops a better understanding of music. A study conducted in 2022 discovered that teaching children to play the piano improves visual memory, which can help improve academic performance.


Fact 10: Death Waltz is Nearly Impossible to Play By Hands Literally

Death Waltz, a popular piano piece composed by John Stump in 1976, is known for its complexity and difficulty. It is almost impossible to play the Death Waltz with hands alone as it requires several simultaneous keystrokes, which are impossible to perform without utilizing both arms. This piece has been performed on stage numerous times but with accompaniment.


In conclusion, the piano is a complex and fascinating instrument. Many people are unaware of the secrets behind this excellent instrument, from its unique and challenging pieces to its incredible ability to help improve academic performance. While mastering the piano is no easy feat, understanding more about it can help you appreciate it in a new way. Whether an amateur or a master, there will always be something new to learn.
