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 ...
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.
Chords are equidistant from the centre of a circle if and only if they are equal in length. The perpendicular bisector of a chord passes through the centre of a circle; equivalent statements stemming from the uniqueness of the perpendicular bisector are: A perpendicular line from the centre of a circle bisects the chord.
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 music stand is a pedestal or elevated rack designed to hold sheets of music in position for reading. [1] [2] Most music stands for orchestral, chamber music or solo orchestra-family instruments (violin, oboe, trumpet, etc.) can be raised or lowered to accommodate seated or standing performers, or performers of different heights. Many types of ...
Chord length c is the length of the chord line In case of an axial flow impeller, the mean radius is defined in terms of hub ( r h {\displaystyle r_{h}} ,inner radius) and tip radius ( r t {\displaystyle r_{t}} ,outer radius) as :
Tablature was common during the Renaissance and Baroque eras, and is commonly used today in notating many forms of music. Three types of organ tablature were used in Europe: German, Spanish and Italian. [1] To distinguish standard musical notation from tablature, the former is usually called "staff notation" or just "notation".
Chord diagrams for some common chords in major-thirds tuning. In music, a chord diagram (also called a fretboard diagram or fingering diagram) is a diagram indicating the fingering of a chord on fretted string instruments, showing a schematic view of the fretboard with markings for the frets that should be pressed when playing the chord.
