Functions Of A Keyboard 2

Q1. The Three Pedals on a Grand Piano are the Una Corda pedal, the Sostenuto pedal and the Sustain pedal.

• The Una Corda pedal softens the note and also changes the quality of the tone.
• The Sostenuto pedal sustains the notes that are being held down when the pedal is pressed, this also leaves any future notes unaffected when the pedal is pressed.
• The Sustain pedal, when pressed, sustains all the damped strings on the piano

Q2. The three main differences between a grand piano and an upright piano are the keys, the pedals and the action.

Action - In a grand piano, the strings lie horizontally and the hammers hit the strings from below, whereas on an upright piano, the strings are held vertically and the hammers hit the strings from the side 

Keys - There are longer keys on a grand piano which provides a greater reach, allowing more precise control, however on an upright piano, the keys are a lot shorter so the touch isn't as good as a grand piano and it makes the subtle control more difficult

Q3. The parameters that you are able to control on a midi keyboard would be the pitch bend, note velocity, modulation controls and the aftertouch..

Q4. If a sustain pedal is used with an electronic keyboard, it controls the electronic systhesis to produce a sustain effect but when the foot is taken off the pedal, the note is cut off co2mpletely, however on a grand piano, when the foot is taken off the pedal, the piano lets go of the note gently so that it still sounds smooth.

Q5. The advantages of shaping midi data using a keyboard would be that your able to play live music whilst being able to alter the sound, the disadvantages would be that
