Western swing. Swing music is a style of jazz that developed in the United States during the late 1920s and early 1930s. It became nationally popular from the mid-1930s. Swing bands usually featured soloists who would improvise on the melody over the arrangement.
Seconds pendulum. A simple pendulum exhibits approximately simple harmonic motion under the conditions of no damping and small amplitude. A seconds pendulum is a pendulum whose period is precisely two seconds; one second for a swing in one direction and one second for the return swing, a frequency of 0.5 Hz. [1]
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 swing (its resonant frequency) makes the swing go higher and ...
The size of an interval between two notes may be measured by the ratio of their frequencies.When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as 1:1 (), 2:1 (), 5:3 (major sixth), 3:2 (perfect fifth), 4:3 (perfect fourth), 5:4 (major third), 6:5 (minor third).
Swing dance is a group of social dances that developed with the swing style of jazz music in the 1920s–1940s, with the origins of each dance predating the popular "swing era". Hundreds of styles of swing dancing were developed; those that have survived beyond that era include Charleston , Balboa , Lindy Hop , and Collegiate Shag .
Western art music. In Western art music or Classical music, a period is a group of phrases consisting usually of at least one antecedent phrase and one consequent phrase totaling about 8 bars in length (though this varies depending on meter and tempo). Generally, the antecedent ends in a weaker and the consequent in a stronger cadence; often ...
The period, the time for one complete oscillation, is given by the expression = =, which is a good approximation of the actual period when is small. Notice that in this approximation the period τ {\displaystyle \tau } is independent of the amplitude θ 0 {\displaystyle \theta _{0}} .
The fundamental frequency, often referred to simply as the fundamental (abbreviated as f 0), is defined as the lowest frequency of a periodic waveform. [1] In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present. In terms of a superposition of sinusoids, the fundamental frequency is the lowest ...
