#music term

• 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.
• 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.
• Aliquot — A specialized term used in acoustics and music to describe an aliquot part of a vibrating string or air column that produces an upper harmonic sound (aliquot tone). In organology and instrument making, it defines the system of aliquot (resonating) strings added to certain pianos (Blüthner system) or violins (like the viola d'amore), which are not struck directly but vibrate freely by sympathy, enriching the musical timbre.
• To the sign — A musical expression and direction originating from Italian (al segno), literally translated as 'to the sign'. It is used in musical scores to instruct performers or the conductor to repeat a previous section starting precisely from the spot marked with a specific graphic symbol (called a 'segno' or 'sign'), serving to optimize the score's graphic space and avoid rewriting the same measures.
• other — A structural word utilized to indicate a person, object, or reality distinct, different, or supplementary to the one previously mentioned. As a neuter noun in music (alto), it defines the lowest female (or boy's) singing voice, ranging between soprano and tenor, or the musical instrument corresponding to this pitch register (such as the viola or alto saxophone).
• Altissimo — A musical term borrowed from Italian that indicates the highest register of a musical instrument (especially the clarinet or saxophone) or the execution of notes in the highest possible octave, exceeding the standard range of the score.
• Altist — A singer with an alto voice (especially a boy or a man using falsetto) or a musician who plays an alto instrument, such as a viola player or a performer on the alto saxophone. As an adjective, it describes a timbre, composition, or instrumental register specific to the alto range.
• Female alto — A female singer whose voice falls within the alto register (pitched between soprano and tenor or contralto) or a woman who plays an instrument in the same acoustic range (viola, alto saxophone).
• Alto — A deep female voice or a boy's voice pitched in a register between soprano and tenor (also called contralto); a musical part or score written for this range. It also designates musical instruments with a timbre corresponding to this range (e.g., alto saxophone, alto flute) or, as an adjective, describes such an acoustic register.
• Love — An archaic variant or stylistic borrowing from Italian designating the feeling of love, an intense romantic passion, or the object of deep affection. In classical musical terminology, the term frequently appears in expression marks (such as 'con amore' - with love, with passion) to guide the sensitive interpretation of a piece.
• Reed — A thin, elastic tongue made of reed, plastic, or metal, used to produce sound through vibration under air pressure in certain wind instruments (such as the clarinet, saxophone, or oboe). It represents the essential acoustic element for controlling timbre, dynamics, and expressive flexibility in generating sound waves specific to woodwinds.
• Reed — A rare spelling variant or unadapted direct loanword for the term anceu; a thin, elastic reed blade made of cane or plastic fixed to the mouthpiece of certain wind instruments to produce sounds through vibration under air pressure.
• Appassionata — The established name of the Piano Sonata No. 23 in F minor, Op. 57, composed by Ludwig van Beethoven, considered one of the most technical and dramatic masterpieces in the entire pianistic literature. As a nominalized adjective, the term originates from Italian and denotes a musical piece or passage performed in a deeply passionate, intense, and emotionally driven manner.
