In Euclidean geometry, the intersecting chords theorem, or just the chord theorem, is a statement that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.
Simple time signatures are usually classified as those with an upper number of 2, 3, or 4. This example shows that each measure is the length of three quarter notes (crotchets). 3 4 is pronounced as "three-four" or "three-quarter time". Compound time signatures In a compound meter, there is an additional rhythmic grouping within each measure.
Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle. If the line extensions (secant lines) of chords AB and CD intersect at a point P, then their lengths satisfy AP·PB = CP·PD (power of a point theorem).
A chord is a line drawn between two points on the circumference of a circle. Look at the centre point of this line. For a circle of radius r, each half will be so the chord will be . The line of chords scale represents each of these values linearly on a scale running from 0 to 60.
Braille music is a complete, well developed, and internationally accepted musical notation system that has symbols and notational conventions quite independent of print music notation. It is linear in nature, similar to a printed language and different from the two-dimensional nature of standard printed music notation.
A guitarist performing a C chord with G bass. In Western music theory, a chord is a group [a] of notes played together for their harmonic consonance or dissonance.The most basic type of chord is a triad, so called because it consists of three distinct notes: the root note along with intervals of a third and a fifth above the root note.

In music, strings are long flexible structures on string instruments that produce sound through vibration. Strings are held under tension so that they can vibrate freely. The pitch (frequency) at which a string will vibrate is primarily related to its vibrating length (also called speaking length [1]), its tension, and its mass per unit of ...
There is some variation in the scale length of an orchestral double bass, generally in the range 41.3–43.3 inches (1,050–1,100 mm). There are also smaller versions of this "full scale" double bass with the same scale length but with a smaller sound box, intended for other musical idioms.
