Music Creation and Performance
Question 1: Describe a harp, and discuss its’ sound and uses.
Answer 1: A chordophone where the strings are suspended vertically and perpendicularly to the soundboard, the harp is triangular in shape with the 3 basic elements of resonator, neck, and strings. The 47 strings are attached directly to the neck through movable tuning pegs, and tunings are pentatonic, tetratonic, heptatonic including diatonic, or chromatic. The double-action harp has 7 strings per octave, and each string can be raised 2 semitones using the pedal system. The manual pedal systems tune the strings to the desired register and pitch. The strings are usually plucked with the thumb and first two fingertips but can also be strummed, struck, or slid upon. The resonator itself can be viewed as a percussion instrument and can be struck by the hand or fingers or hooked rattles.
There are lots of good resources about Music Creation that you can find available.
Question 2: Describe a piano, and discuss its’ sound and uses.
Answer 2: Originally referred to as the pianoforte, the modern piano is able to create music with dynamics such as soft and loud whereas the harpsichord had only one dynamic. Pressure applied by the musician at the outer ends of the keys causes connected wires to strike a hammer against tuned strings that vibrate. The musical range for the piano is 7 1/3 octaves from A2 to C?. The term itself refers to the strings, area over which the strings are stretched or the soundboard, the iron frame to which the strings are attached, and the structure of keys and hammers or piano action in a horizontal space usually enclosed in a solid case.
Question 3: Describe an organ, and discuss its’ sound and uses.
Answer 3: The organ is made up of a keyboard attached to 1 or more sets of pipes. The sets of pipes or stops combine with the action of the organ to allow the musician to combine the sounds produced by the different sets of pipes during the performance. The organ’s pipework is properly voiced and scaled with wind supply and wind chests for projection, and the organ includes the keys, stop actions, and case. The pipes are made of metal or wood and are either classified as flue or reed depending on the type of sound created. Flue pipes can be divided into stopped flute, chimney flute, gemshorn, and principal. Reed pipes can be divided into 2 types of trumpet pipes.
