• 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.
• 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.
• 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.
