I’m loving the AKAI MPK Mini MK3 for its compact design and the range of controls. It’s one of my essential tools. The velocity-sensitive keys and MPC-style pads are great for making beats, while the thumbstick and knobs give me precise control.

How does a prepared piano work?

So here’s where it gets interesting. The first step to finding out how a prepared piano works is understanding that a prepared piano is no ordinary piano. It’s whimsical, it’s experimental, and it’s all about crafting unique, wacky sounds. You take that beautiful classic grand piano and add bits and bobs like erasers, screws, coins, or plastic. 

Each object alters the piano strings to create a new, unique sound. That’s why a prepared piano can sound like nothing you’ve ever heard before. It’s like that mashup version of Linkin Park and Jay Z’s “Numb/Encore.” A total curveball!

Here’s a table outlining the dos and don’ts of using a prepared piano:

Experiment with various objects for unique sounds.Don’t use objects that can damage the piano strings or mechanisms.
Secure the objects properly to prevent accidents.Don’t use excessive force when placing objects on the strings.
Explore different techniques for sound manipulation.Don’t neglect proper maintenance and care for the piano.
Document your preparations for future reference.Don’t leave objects on the strings for extended periods.
Embrace creativity and push the boundaries.Don’t force the piano beyond its physical limitations.

Who invented the prepared piano?

Los Angeles-based composer John Cage is hailed as the genius who invented the prepared piano. The man changed the game, simple as that. He wanted a more percussion-like sound for his dance piece Bacchanale but only had a grand piano to work with.

So, Cage decided to think outside the box (or inside the piano, to be exact) and began inserting objects into the instrument to transform its sound. Fun fact: his music teacher influenced him by plucking and strumming piano strings to create unique sounds.

Why use a prepared piano?

Now you might ask, “why on earth would I want to stuff random objects into my grand piano?” Well, because you can change the game. The main purpose of a prepared piano is to manipulate the sound of the instrument. Do you want to create a more percussive sound? No problem. You’re looking for an eerie, suspenseful effect? Easy. With a prepared piano, the possibilities are endless, and you’re not bound to the piano’s usual range of sounds.

Is playing a prepared piano different from a regular piano?

Yes, it is! With a prepared piano, the changes to the strings mean that each key can have a unique sound and timbre. So, playing a prepared piano can be a surprise, with each key strike unleashing something unexpected. It’s a bit like having a magic box, y’know? No, it’s nothing like Harry Potter, but honestly, it’s akin to discovering Narnia in your cupboard. It’s like, “Yo, where did THAT sound come from?”

What are some notable pieces done on a prepared piano?

Ready to give your ears a crazy musical journey? Check out these famous pieces:

  • Bacchanale by John Cage: It’s the OG of prepared piano pieces and takes you on a wild ride.
  • Sonatas and Interludes, also by John Cage: This collection was a deliberate effort to use the prepared piano in a more controlled, experimental setting.
  • “Little Fishes” by Brian Eno: Bet you didn’t expect the guy from Roxy Music to be on this list, did you? Prepare to be blown away.
  • Drukqs by Aphex Twin: He’s more known for his electronic beats, but this album also features some killer prepared piano tracks.
  • The Prepared Piano by Hauschka: This entire album is a tour de force of the possibilities of a prepared piano.

What are the advantages and disadvantages of using a prepared piano?

Using a prepared piano can offer unique artistic opportunities, but it also comes with certain drawbacks. Here are the advantages and disadvantages of using a prepared piano:


  • Expanded sound palette: Prepared piano techniques can produce a wide range of unconventional sounds and textures, allowing composers and performers to explore new sonic possibilities that are not achievable with a traditional piano.
  • Enhanced expressiveness: The added objects on the strings alter the piano’s timbre and resonance, offering greater expressive potential. This can evoke specific moods, atmospheres, or certain emotions that may not be achievable with a regular piano.
  • Increased creativity: Prepared piano encourages experimentation and pushes the boundaries of traditional composition. It challenges composers and performers to think outside the box and explore unique ways to create music.
  • Customizability: Different objects and preparations can be used on the piano, providing the opportunity to customize the instrument’s sound to suit specific musical compositions or concepts.


  • Risk of damage: Placing objects on the strings or inside the piano carries the risk of damaging the instrument if not done properly. Objects that are too heavy or sharp can cause scratches, dents, or even break the strings.
  • Limited repertoire: Prepared piano techniques may not be suitable for all types of music. The unique sound qualities produced by the preparations may limit the range of musical styles and genres in which the instrument can be effectively used.
  • Maintenance challenges: Maintaining a prepared piano requires additional effort. The objects used in preparations must be regularly checked for any wear or damage, and the piano may require specialized cleaning or adjustments.
  • Accessibility and availability: Prepared pianos may not be available in all settings or performance venues. This can limit the opportunities for musicians to perform on a prepared piano, especially outside of specialized contemporary music contexts.

It’s important to weigh these advantages and disadvantages when deciding to use a prepared piano, considering the specific artistic vision, musical context, and the availability of resources and expertise for preparation and maintenance.
