The 15th century was the century which spans the Julian calendar dates from 1 January 1401 (represented by the Roman numerals MCDI) to 31 December 1500 (MD).

as well as range, and a classically trained solo contralto would usually have a range greater than that of a normal choral alto part in both the upper and lower ranges. However, the vocal tessitura of a classically trained contralto would still make these singers more comfortable singing in the lower part of the voice. A choral non-solo contralto may also have a low range down to D
3 (thus perhaps finding it easier to sing the choral tenor part), but some would have difficulty singing above E
5. In a choral context mezzo-sopranos and contraltos might sing the alto part, together with countertenors, thus having three vocal timbres (and two means of vocal production) singing the same notes.
The use of the term "alto" to describe solo voices is mostly seen in contemporary music genres (
pop, rock, etc.) to describe singers whose range is lower than that of a mezzo-soprano but higher than that of a true contralto, and is very rarely seen in classical music outside of soloists in choral works. In classical music, most women with an alto range would be grouped within mezzo-sopranos, but many terms in common usage in various languages and in different cultures exist to describe solo classical singers with this range. Examples include contralto, countertenor, ''
