Instrumentation • This work is for live guitar, accompanied by parts for 7 guitars and 2 bass guitars that have been prerecorded. • The live guitar is amplified to blend in with the backing tape. Structure The music builds up in 3 layers: 1. A syncopated quaver motif is introduced in the live guitar and top 4 guitar parts, one part at a time. 2.
It’s essentially an arrangement of sounds and silences, with certain sounds more pronounced than others. Generally it is very patterned and sits behind more melodic instruments, such as a lead guitar, in the mix of a song and acts as a foundation. It tends to
3. How do the three parts of a speaker--electromagnet, cone, and diaphragm--work together to make sound? The three parts come together and make sound by the audio signals being sent through a wired coil and a piece of iron called an electromagnet. The electromagnet is connected to a cone or diaphragm which when the electromagnet
Sound travels faster through warm air than cold air because the molecules in warm air vibrate faster. Resonance is when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion which is forced vibration. An example would be if two tuning forks with the same natural frequency are set across from each other, then one tuning fork is hit with a rubber mallet which causes them both to vibrate because the surrounding air particles are set into vibratinoal motion. Frequency is the number of waves that pass a fixed place in a given amount of time. Picture: When a tuning fork is stamped 440 HZ means that the frequency and the pitch of that fork is 440 HZ.
An important element of baroque instrumentation, the combination of a bass instrument (usually from the string family), such as the cello or double bass, paired with a keyboard instrument such as the harpsichord or the organ. These two instruments (the bass instrument and the keyboard instrument) read the same line of music, a bass line, so that the keyboard player improvised chords and other accompanying figures in his or her right hand. The basso continuo provided the rhythmic and harmonic support for virtually all baroque music. Bassists are a part of the rhythm section. The rhythm section consists of the bassist, drummer, and other instruments playing a
3). Normally singing consists of a group of singers who each sing different notes. However, the throat singing technique allows one person to be able to sing many different notes. Through vocalization techniques a singer can produce unique harmonies by using the throat’s resonance characteristics. A singer must use precise movement of the lips, tongue, jaw, velum, and larynx (Smithsonian, par.
Section 13-1: Sound Waves -When a tuning fork is hit, the prong swings to the right and the molecules are pressed closer together. compression-the region of high molecular density and air pressure -When the prong moves to the left, the molecules to the right spread apart. rarefaction-area of low air pressure and density -As the tuning fork continues to vibrate, it sends out a series of compressions and rarefactions in all directions like ripples in a pond. -Sound waves are longitudinal. audible sound waves-what humans hear; between 20 and 20,000 Hz infrasonic-less than 20 Hz ultrasonic-higher than 20,000 Hz; used to produce images inside the body because short wavelengths are easily reflected off a small object ex.-Dolphins use short
75uS is the time constant used for a high-pass filter to enhance the high frequency audio before transmission to help reduce noise upon reception. The PLL is the portion of the IC which locks your chosen transmission frequency to the crystal reference X1. The PLL portion also contains an oscillator circuit which works in conjunction with the external parts of D5 and the STUB (that weird trace on the back of the board). D5 is called a varactor diode, and is a special variety of diode that is connected backwards. As a reverse DC voltage is applied across the diode, its capacitance varies.
86. ANS: The wavelength decreases; the amplitude and speed are not affected. 87. ANS: Light undergoes refraction, diffraction, and interference like all waves. Its energy depends on frequency, which is how a particle behaves.
They are: a stretched string made from high-carbon steel, a keyboard, and a blow. The strings are the component that produces the sound, the keyboard is used for manipulating the strings and the blow is the process of hammers striking the strings and causing them to vibrate (C. A. Browne). This process creates the sound. Most of these mechanics are hidden beneath a lid that can be propped up at different levels. How many levels differs with the makers.
