• Animando — A musical execution directive requiring the performer to gradually increase the animation, vivacity, and dynamism of the piece, often through a slight acceleration of the tempo and an increase in sound intensity. This term guides the emotional transition of a composition toward a more passionate, lively, or agitated state, adding expressiveness to the musical discourse.
• Animato — A musical performance directive requiring the player to perform in an enlivened, lively, moved manner full of dynamic expressiveness. Unlike 'animando', which implies a gradual process of acceleration or intensification, this term establishes a stable mood and tempo characterized by vibrant energy right from the beginning of the respective passage.
• Annotation — The act of annotating and its result; a structural process through which explanatory notes, metadata tags, comments, or critical interpretations are added to a text, document, or raw data set (images, audio, video). In machine learning and artificial intelligence, this process is essential for creating training data sets, enabling algorithms to recognize specific patterns, objects, or grammatical structures.
• Annotation — An explanatory note, short comment, addition, or critical observation written in the margin of a text, legal document, or book to clarify, interpret, or highlight a specific informational structure. In modern terminology and computer science, it represents a metadata tag applied to a digital element to assign a precise contextual meaning.
• Aperto — A musical term of performance direction indicating that a piece must be executed in an open, clear, broad, and bright manner. In a broader literary sense, it stems from foreign phrases meaning unfolding without restrictions or secrets (e.g., in aperto).
• Arco — A term used as a direction in instrumental music, instructing performers of stringed instruments (violin, viola, cello, double bass) to resume playing the notes with the bow, following a structural section where the strings were plucked with the fingers (pizzicato).
• Aretino — The surname of the famous Italian writer, poet, and satirist Pietro Aretino, a prominent figure of the Renaissance, renowned for his biting wit, erotic writings, and immense political influence over European courts, earned him the moniker 'The Scourge of Princes'. In a structural-eponymic sense, the term also refers to an incisive, dogma-free satirical style, or references the medieval composer Guido of Arezzo (Guido Aretinus), the inventor of the modern musical staff notation system.
• Marking — The act of marking, designating, or noting something; an official document, proof, administrative marking, or historical assignment of a property or fiscal tax in medieval deeds. The term was also used to denote an explanatory note written on the margin of an old legal text.
• Asymptotic — Having the character of an asymptote, relating to an asymptote; continuously and infinitely approaching a certain value, curve, or structural limit without ever touching it directly in finite time. In computer science, it describes the runtime complexity of algorithms at large data volumes, and in statistics, the metric behavior of probability distributions.
• Assai — A musical term of Italian origin used as a tempo or dynamic modifier, meaning 'very', 'quite', or 'considerably'; it is always placed alongside another movement term (for instance, 'allegro assai' - very fast, 'adagio assai' - very slow) to intensify or nuance the execution speed of a score.
• Autographic — Pertaining to or relating to an autograph or to autography; executed by direct handwriting or multiplied using the lithographic technique of autographic transfer. In aesthetics and art theory (Nelson Goodman), it describes a work whose authenticity depends on the direct physical execution by the author (such as a painting), as opposed to allographic arts (such as music or literature), which can be reproduced through notation without losing their status as an original.
