The word "key action" is spelled with two syllables. "Key" is pronounced as /ki/ with the "k" sound at the beginning, followed by the "ee" long vowel sound. "Action" is pronounced as /ˈæk.ʃən/ with the stress on the first syllable, and a short "a" sound. The "c" is pronounced as /ʃ/, and the "t" at the end is silent. "Key action" is a term used in music, referring to the mechanism that connects the keys of a keyboard instrument, such as a piano or organ, to the hammers or other parts that produce sound.
Key action refers to the mechanism in a musical instrument, especially keyboard instruments such as pianos, organs, and synthesizers, that allows the player to produce sound by depressing the keys. It involves the sensitive and precise movement of the keys, translating the player's touch into the corresponding musical notes.
In the case of pianos, key action is responsible for the connection between the keyboard and the hammers that strike the strings. When a key is pressed, the action system transfers the energy of the player's finger to the hammer, causing it to strike the string, which then vibrates to produce sound. The quality of the key action greatly influences the feel and responsiveness of the instrument, and it is often a crucial factor considered by performers and musicians when selecting a particular instrument.
The key action can vary in design and type, depending on the instrument. Traditional acoustic pianos usually feature a mechanical key action, comprising a series of levers and springs. In contrast, digital keyboards and electronic instruments may use electronic sensors and mechanisms to replicate the touch and feel of acoustic instruments.
Overall, key action is an essential element in the functionality and playability of keyboard instruments, providing the means for musicians to express their musical ideas and create the desired sound through the physical interaction with the keys.
The etymology of the term "key action" is derived from various sources.
The word "key" originated from the Old English word "cǣg", which referred to a device used to unlock or lock something. This term later evolved into Middle English "keye" and eventually transformed into its current form, "key".
"Action" comes from the Latin word "actio", which means "a doing" or "a movement". This Latin term was borrowed into Middle English as "accion" or "action", referring to the performance of a movement or a physical act.
When combined, "key action" refers to the mechanical system or mechanism of a musical instrument, particularly in the context of a keyboard instrument such as a piano. It describes the responsive movement or action of the keys when pressed, resulting in sound production.
