Prepared Piano: From John Cage to Modern Production

The prepared piano is a unique and intriguing musical instrument used in various music genres, including classical, avant-garde, and experimental music. It is a standard piano that has had its sound altered by inserting various objects between or onto the strings of the instrument. This technique creates a range of new sounds and tones that are not typically associated with unaltered pianos.

Definition of Prepared Piano

what is prepared piano

A prepared piano is a standard acoustic piano modified by placing various materials on or between strings, hammers, or dampers. These materials can include rubber bands, screws, bolts, pieces of wood or metal, paper clips, and other objects that create new sounds when the keys are pressed. This technique alters the natural resonance and timbre of the instrument, creating an entirely new sound world for composers and performers to explore.

Brief History of Prepared Piano

The concept of preparing a piano dates back to the early 20th century when composers began experimenting with unconventional methods of producing sound. American composer John Cage used prepared piano in his 1940 piece “Bacchanale,” which involved placing screws and bolts between the strings to create percussive effects.

Cage went on to develop this technique further in his 1948 work “Sonatas and Interludes,” which featured a fully prepared piano with objects placed on every single string.

Other notable composers who have used prepared piano in their works include George Crumb, Henry Cowell, and Karlheinz Stockhausen. Today, it remains an important tool for contemporary composers who seek unconventional ways to produce new sounds in their compositions.

How a Prepared Piano Works

Preparing a piano involves inserting various objects between the strings or attaching them to the instrument’s hammers, dampers, or other parts to alter its sound. This results in an entirely different timbre than what you would get from playing an unprepared piano.

The preparation process is performed by experienced technicians who use a variety of materials such as rubber, screws, bolts, erasers, and paper clips. The choice of materials affects the sound produced by the prepared piano.

For example, objects like screws and bolts produce more percussive sounds while rubber or felt creates a more muted effect. The objects used are carefully placed in specific locations to achieve desired results.

For instance, placing objects on strings can create buzzes or rattles while inserting them next to hammers can create unusual overtones. When preparing a piano for performance, it’s essential to keep in mind that not all pianos are suitable for preparation.

Some older pianos may have weaker frames that may not be able to handle added pressure from inserted objects. It’s best to consult with an experienced technician before attempting any preparations yourself.

Explanation of the Preparation Process

The preparation process involves several steps:

1) Assessing the condition of the piano: Before preparing a piano, it’s crucial to ensure that its parts are in good working order.

2) Selecting appropriate preparation materials: As previously mentioned, various materials can be used when preparing a piano depending on the desired sound.

3) Inserting selected elements into appropriate locations: Once you’ve selected your preferred materials for preparation and assessed your piano’s condition and suitability for this purpose (if needed), you will need to place them into their designated locations within your instrument.

4) Tuning your prepared piano: After you’ve prepared your instrument with various materials and played around with sounds enough times until you feel satisfied with the result, it’s essential to tune the piano appropriately.

The preparation process can be challenging and requires a great deal of skill and experience. Therefore, it’s best to leave such work in the hands of an experienced technician.

Examples of Common Materials Used for Preparation

Many different materials can be used when preparing a piano, each having a unique effect on the sound produced. Some common materials include:

– Rubber: This material is frequently used to create a soft dampening effect on strings or hammers. – Screws and bolts: These objects are inserted between strings or next to hammers to create percussive effects.

– Felt: Placing felt between strings can produce muted sounds. – Erasers: These are sometimes placed on hammers to muffle their sound.

– Paper clips: Paper clips produce unusual overtones when placed on strings. These materials can be used in various combinations and placed in different locations within the instrument, resulting in endless possibilities for creating new soundscapes with your prepared piano.

The Sound of a Prepared Piano

One of the prepared piano’s most fascinating aspects is its unique sound. While a traditional piano has a distinct, recognizable sound, a prepared piano can produce an entirely different range of tones and textures.

The preparation process alters the sound by adding objects to the strings inside the piano, which can create new harmonics and dampen certain frequencies.

Comparison between a traditional piano and a prepared piano

A prepared piano often has a more percussive and metallic tone than a traditional piano. The added objects can produce sounds that resemble percussion instruments such as wood blocks, maracas or even drums.

The resonance of notes can also be changed, with some sounding shorter or longer than they would on an unprepared instrument. The range of dynamics is also wider in some cases, with some notes being dulled so much that they barely make any sound at all while others are amplified and resonate for longer periods.

Description of unique sounds produced by a prepared piano

Some unique sounds that can be produced on a prepared piano include buzzing or rattling noises resembling insects or small animals scurrying about inside the instrument. Other preparations produce harmonics that fade in and out like ghostly echoes or metallic chimes.

Some composers have even used preparations to mimic specific sounds such as water dripping or machinery whirring. The possibilities are nearly endless when it comes to what kind of sounds you can create on a prepared piano; it all depends on how creative you are with your preparations.

Famous Composers Who Used Prepared Piano in Their Work
