stringhe

Stringhe is the plural form of stringa in Italian and can refer to several different concepts depending on the context. In computing, a stringa or string is a sequence of characters used to represent text. Strings are fundamental data types in many programming languages and are typically ordered, have a finite length, and are encoded using schemes such as Unicode. Operations on strings commonly include concatenation, slicing, length retrieval, indexing, and searching. Some languages treat strings as immutable, others as mutable, which affects how they can be modified after creation.

In music, stringhe are the strings of musical instruments such as guitars, violins, cellos, and pianos. Strings are made from materials like gut, steel, or nylon and produce sound when they vibrate due to excitation by plucking, bowing, or striking. The pitch is influenced by tension, length, and thickness; materials and construction determine timbre and sustain. The design and tuning of stringed instruments are central to their musical character.

In mathematics and theoretical computer science, a stringa is a finite sequence of symbols from an alphabet. The empty string, often denoted ε, represents a sequence of length zero. Strings are combined through concatenation and used to model words in formal languages, coding theory, and automata theory. Notation such as Σ* denotes the set of all finite strings over a given alphabet Σ.

Etymology and usage: stringhe derives from stringa, which traces back to Latin stringa, meaning a line or thread. In Italian, the term is widely used across computing and everyday language to refer to multiple instances of a string.
