Girl With A Musical Instrument

Many instruments have their range as part of their name: soprano saxophone, tenor saxophone, baritone horn, alto flute, bass guitar, etc. Additional adjectives describe instruments above the soprano range or below the bass, for example: sopranino saxophone, contrabass clarinet.
When used in the name of an instrument, these terms are relative, describing the instrument's range in comparison to other instruments of its family and not in comparison to the human voice range or instruments of other families. For example, a bass flute's range is from C3 to F♯6, while a bass clarinet plays about one octave lower.
