Copedent is a term used to describe the tuning and pedal arrangement on a pedal steel guitar and is unique to that instrument. Typically expressed in the form of a table or chart, the word is a portmanteau of " c h o rd– ped al–arrangem ent and is pronounced "co-PEE-dent". [ 1 ]
Another form of coupler found on some large organs is the divided pedal. This is a device that allows the sounds played on the pedals to be split, so the lower octave (principally that of the left foot) plays stops from the pedal division while the upper half (played by the right foot), plays stops from one of the manual divisions.
The first use of pedals on a pipe organ grew out of the need to hold bass drone notes, to support the polyphonic musical styles that predominated in the Renaissance. Indeed, the term pedal point, which refers to a prolonged bass tone under changing upper harmonies, derives from the use of the organ pedalboard to hold sustained bass notes. [2]
Modern pianos usually have three pedals, from left to right, the soft pedal (or una corda), the sostenuto pedal, and the sustaining pedal (or damper pedal). Some pianos omit the sostenuto pedal, or have a middle pedal with a different purpose such as a muting function also known as silent piano .
The High Speed Transport destroyer conversions (APD/LPR), the Landing Platform Docks (LPD), and all new ships with a full flight deck (LPH, LHA, LHD) would meet this criterion. The other major types would see relatively small numbers of new ships constructed with this 20 knot requirement, with the last appearing in 1969.
The clutch pedal controls the pressure plate (clutch engaged – the clutch pedal is not being pressed) or not connected to the engine (clutch disengaged – the clutch pedal is being pressed down). When the engine is running and the clutch is engaged (i.e., clutch pedal up), the flywheel spins the clutch pressure plate and hence the transmission.
The combination of governed engine speed with foot throttle override is in many ways similar to a modern cruise control. In spite of this development, steering column mounted hand throttles remained common, especially in mass-produced cars such as the Ford Model T. [7] Later cars used both a foot pedal and a hand lever to set the minimum throttle.
