The Power of Music
- We don’t know everything about how music effects the brain, but we do know that music makes the brain work to process it.
- Listening to any music that your brain has to process can have a positive effect on your brain. This is why you feel better after listening to your favorite song.
Electric pianos produce sounds mechanically and the sounds are turned into electrical signals by pickups. Unlike a synthesizer, the electric piano is not an electronic instrument, but electro-mechanical. The earliest electric pianos were invented in the late 1920s; the 1929 Neo-Bechstein electric grand piano was among the first. Probably the earliest stringless model was Lloyd Loar’s Vivi-Tone Clavier.
The pipe organ is a musical instrument commonly used in churches or cathedrals that produces sound by driving pressurized air (called wind) through pipes selected via a keyboard. Because each organ pipe produces a single pitch, the pipes are provided in sets called ranks, each of which has a common timbre and volume throughout the keyboard compass.
A player piano (also known as pianola or autopiano) is a self-playing piano, containing a pneumatic or electro-mechanical mechanism that operates the piano action via pre-programmed music perforated paper, or in rare instances, metallic rolls.
String piano is a term coined by American composer-theorist Henry Cowell (1897–1965) to collectively describe those pianistic extended techniques in which sound is produced by direct manipulation of the strings, instead of or in addition to striking the piano’s keys. Pioneered by Cowell in the 1920s, such techniques are now often called upon in the works of avant-garde classical music composers.
String piano compositions can involve a wide range of techniques. Among those employed by Cowell, the first major proponent of the approach, are:
- plucking (pizzicato)
- flicking back and forth across a string with a fingernail (similar to a mandolin tremolo)
- sweeping chromatically across the strings with the fingers
- sweeping across the strings with the flat of the hand (producing a tone cluster)
- sweeping along one or more strings with the flesh of the finger(s)
- scraping along one or more strings with the fingernail(s)
