• Abendmusik (music therapy style) — A cultural term of German origin designating a series of evening musical performances, transposed into art therapy, clinical music therapy, and sleep management. In neuro-psychiatry protocols, the concept of abendmusik is used to describe structured interventions using relaxing, low-frequency music with steady rhythms, performed in the latter part of the day. The therapeutic purpose consists in reducing evening psychomotor agitation (sundowning syndrome found in dementias), inducing cortical relaxation, lowering cortisol levels, and facilitating the onset of sleep in patients with chronic anxiety or insomnia.
• Acute — Manifesting intensely, suddenly, and for a short duration, being the opposite of chronic conditions (in medicine); a high-pitched, thin, or sharp sound (in music and phonetics); also, describes an angle smaller than 90 degrees (in geometry). Figuratively, the term expresses a piercing sensation, a pressing crisis, or an extremely fine and sharp sensitivity of the senses.
• Adagietto — A musical term indicating a fairly slow tempo, slightly faster and more moving than adagio, but slower than andante; also, it designates a piece or a part of a symphonic composition written in this rhythm. This structural indication grants the piece a melancholy and fluid nuance, famously illustrated by the fourth movement of Gustav Mahler's Fifth Symphony.
• Adagio — A musical term indicating a slow, leisurely, and solemn tempo, situated between largo and andante; also, it designates a piece or part of a composition written in this rhythm or a suite of slow movements performed in classical ballet. This structural movement emphasizes expressiveness, impeccable muscular control, and the fluidity of melodic lines.
• Adam de la Halle — A medieval French poet, composer, trouvère, and playwright of the 13th century, considered one of the founders of secular theater in France; author of the famous musical play 'The Play of Robin and Marion' (Le Jeu de Robin et de Marion). This structural figure in art history excelled in early polyphonic composition and monophony, laying the foundations of medieval comic opera by merging spoken dialogue with lyrical musical sections.
• Addolcendo — A musical execution term of Italian origin, literally meaning 'sweetening' or 'softening'. It instructs the performer to transition smoothly toward a warmer, more melodious, soft, and velvety sound emission, gradually reducing any harshness or intensity to enhance the lyrical expressiveness of the passage.
• Addolorando — An expressive term used as a performance indication in musical notation, instructing the performer to render the respective passage in a painful, mournful manner, full of sadness and deep suffering. This stylistic indicator, borrowed from Italian, guides interpretation dynamics and sensitivity to convey an emotional state marked by grief or compassion.
• Adirato — A niche musical term or archaic lexical borrowing adapted from the Italian language indicating the performance of a melodic sequence in an angry, furious, irritated, or wrathful manner. As a rare adjective in old literary texts of refined influence, it describes the state of a character seized by intense and uncontrollable anger.
• Aeolsharfe — Aeolian harp; a stringed musical instrument invented or rediscovered during the Baroque period and intensely used in the Romantic Era, structurally designed to produce harmonic sounds exclusively under the direct action of natural air currents. The term originates from German ('Aeolsharfe'), serving as a literary and musical symbol of the direct connection between nature and spontaneous artistic creation.
• Equale — Equale; a short musical piece written for an ensemble of identical instruments or equal voices, historically used in Austria and Germany starting from the 18th century, especially during funeral ceremonies or religious processions. As a Latin adjective, it indicates a state of structural equality or rhythmic uniformity in an old choral composition.
• Aerophone — As a noun, it represents any musical instrument (such as the flute, trumpet, or organ) in which sound is produced exclusively by the vibration of an insufflated mass of air, without the aid of strings or tensioned membranes. The classification belongs to the Hornbostel-Sachs system. As an adjective, it describes a system or device capable of transmitting sound via air currents.
• Atonic element — A specialized technical term describing a vocalic structure or syllabic unit lacking a distinct or nuanced musical tone; a syllable or word that loses its melodic independence in the flow of speech.
• Affettuoso — An Italian musical direction instructing the performer to play a piece with deep feeling, sentiment, and warmth; it demands a tender, expressive, and affectionate interpretation, often associated with slower, lyrical movements.
• Affrettando — An Italian musical direction instructing the performer to increase the tempo in a hurried, rushing, or pressing manner, carrying an implication of excitement or heightened nervous energy.
• Tone-deaf — A person lacking musical ear, unable to correctly perceive sound pitch or reproduce a melody; medically, it refers to an individual affected by aphonia (loss of voice). Informally, it describes someone completely incompetent or ignorant in a specific field.
• Tone-deaf (female) — Feminine form of 'afon'. It designates a female lacking a musical ear, unable to perceive sound pitch or reproduce a melody; clinically, it describes a woman who has lost her voice due to a laryngeal condition. Informally, it highlights a female completely ignorant in a field.
• Afterbeat — A neologistic musical term, borrowed from English, denoting a rhythmic accent placed on the weak beats of a measure (beats two and four in a four-beat measure). This structural technique is fundamental in musical genres such as jazz, reggae, ska, rhythm and blues, or electronic music, giving the composition a dynamic syncopated effect or continuous pulsation.
• Agiato — A technical musical term of manner or execution indication from Italian, meaning easily, comfortably, quietly, or at ease; it prescribes the performance of a composition or musical fragment in a moderate, relaxed tempo, free of structural haste.
• Agitato — A musical term of Italian origin used as an execution directive, requiring the respective fragment or piece to be performed in an agitated, restless, tense, and dramatically passionate manner. In a structural compositional sense, it guides the tempo and dynamics of performance to convey a state of powerful emotional unrest.
• Agogic — Relating to agogics or fluctuations in musical tempo; it describes the subtle, expressive variations in speed or rhythm (such as rubato) introduced by a performer to enhance the emotional delivery, bypassing mechanical strictness.
