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 ...
Terminal symbols are symbols that may appear in the outputs of the production rules of a formal grammar and which cannot be changed using the rules of the grammar. Applying the rules recursively to a source string of symbols will usually terminate in a final output string consisting only of terminal symbols. Consider a grammar defined by two rules.
where A, B, and C are nonterminal symbols, the letter a is a terminal symbol (a symbol that represents a constant value), S is the start symbol, and ε denotes the empty string. Also, neither B nor C may be the start symbol, and the third production rule can only appear if ε is in L(G), the language produced by the context-free grammar G.
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 caesura is also described by its position in a line of poetry: a caesura close to the beginning of a line is called an initial caesura, one in the middle of a line is medial, and one near the end of a line is terminal. Initial and terminal caesurae are rare in formal, Romance, and Neoclassical verse, which prefer medial caesurae.
A symbol (♮) that cancels the effect of a sharp or a flat naturale (nat.) Natural (i.e. discontinue a special effect, such as col legno, sul tasto, sul ponticello, or playing in harmonics) N.C. No chord, written in the chord row of music notation to show there is no chord being played, and no implied harmony Nebenstimme (Ger.)
A context-sensitive grammar is a noncontracting grammar in which all rules are of the form αAβ → αγβ, where A is a nonterminal, and γ is a nonempty string of nonterminal and/or terminal symbols. However, some authors use the term context-sensitive grammar to refer to noncontracting grammars in general. [1]
In some European countries (particularly France), pop and jazz musicians often use so-called "chord grids" that show in a graphical way the chord progression. To illustrate, below is an example of two-part tunes, each eight bars long. Each square stands for a bar, while the "•/•”symbol means to stay on the same chord as the previous bar.
