Musical Terminology
1. The word that refers to the tones in between and including the highest and lowest pitches you can sing is called your vocal range. This range is usually defined by the specific notes that a singer can produce, from the lowest note they can sing to the highest note. For instance, a typical vocal range for a soprano singer might include pitches from C4 (middle C) to C6 (high C), giving a span of two octaves.
2. Singing a melody without accompaniment or harmony is referred to as a cappella. This term originates from the Italian phrase meaning 'in the manner of the chapel' and denotes performances that rely solely on the human voice. Groups and choirs often perform pieces a cappella to highlight vocal harmonies and simple melodies without any instrument support.
