The word "alto" appears to be remarkably versatile in literature, functioning both as an adjective denoting physical or metaphorical height and as a musical term signifying a particular vocal or instrumental register. In poetic works like Dante’s Divine Comedy, "alto" evokes images of elevated cities, lofty seats, or high paths, underscoring a sense of grandeur and transcendence ([1], [2], [3], [4], [5], [6]). Meanwhile, in musical and technical contexts, "alto" refers to voice types or instrument ranges—from the counter-tenor to the alto trumpet—emphasizing auditory rather than spatial height ([7], [8], [9], [10], [11], [12]). In Spanish texts, the term is employed both to describe elevated physical positions and a commanding or distinct mode of expression ([13], [14], [15], [16], [17], [18]). This rich semantic field highlights "alto" as a term that seamlessly spans the realms of poetry, music, and everyday description.
