Pushing a person in a swing is a common example of resonance. The loaded swing, a pendulum, has a natural frequency of oscillation, its resonant frequency, and resists being pushed at a faster or slower rate. A familiar example is a playground swing, which acts as a pendulum. Pushing a person in a swing in time with the natural interval of the ...
Acoustic resonance is also important for hearing. For example, resonance of a stiff structural element, called the basilar membrane within the cochlea of the inner ear allows hair cells on the membrane to detect sound. (For mammals the membrane has tapering resonances across its length so that high frequencies are concentrated on one end and ...
The most familiar examples of acoustic resonators are in musical instruments. Every musical instrument has resonators. Every musical instrument has resonators. Some generate the sound directly, such as the wooden bars in a xylophone , the head of a drum , the strings in stringed instruments , and the pipes in an organ .
For example, intensional definitions list aspects or elements that make up their subject. Some definitions refer to music as a score, or a composition: [ 18 ] [ 7 ] [ 19 ] music can be read as well as heard, and a piece of music written but never played is a piece of music notwithstanding.
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
For example, the clarinet and saxophone have similar mouthpieces and reeds, and both produce sound through resonance of air inside a chamber whose mouthpiece end is considered closed. Because the clarinet's resonator is cylindrical, the even-numbered harmonics are less present. The saxophone's resonator is conical, which allows the even ...
The resonance characteristics of a musical instrument obviously will vary with different materials and the amount of material used will have some effect. [ 3 ] Of special importance to singing is the relationship of the surface of a resonator to its tonal characteristics.
Meaning respectively "measured song" or "figured song". Originally used by medieval music theorists, it refers to polyphonic song with exactly measured notes and is used in contrast to cantus planus.
