A time signature (also known as meter signature, [1] metre signature, [2] and measure signature) [3] is a convention in Western music notation that specifies how many note values of a particular type are contained in each measure ( bar ). The time signature indicates the meter of a musical movement at the bar level.
4 time. The term "quarter note" is a calque (loan-translation) of the German term Viertelnote . In Romance languages , the name of this note and its equivalent rest is usually derived from the Latin negra meaning 'black'—the Catalan, French, Galician, and Spanish names for the note (all of which mean 'black') derive from the fact that the ...
This attribute of a number, being exclusively either zero (0), positive (+), or negative (−), is called its sign, and is often encoded to the real numbers 0, 1, and −1, respectively (similar to the way the sign function is defined). [1] Since rational and real numbers are also ordered rings (in fact ordered fields ), the sign attribute also ...

Less-than sign. The less-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the left, <, has been found in documents dated as far back as the 1560s. In mathematical writing, the less-than sign is typically placed between two values ...
List of musical symbols. 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 ...
Calculus. In mathematics, the harmonic series is the infinite series formed by summing all positive unit fractions : The first terms of the series sum to approximately , where is the natural logarithm and is the Euler–Mascheroni constant. Because the logarithm has arbitrarily large values, the harmonic series does not have a finite limit: it ...
Here, the plus-or-minus sign indicates that the term may be added or subtracted depending on whether nis odd or even; a rule which can be deduced from the first few terms. A more rigorous presentation would multiply each term by a factor of (−1)n, which gives +1 when nis even, and −1 when nis odd. In older texts one occasionally finds (− ...
