# What is the name for a group of five?

The title seems off-topic, and I don't know what to tag. Could anyone edit it?

I see group of four is quartet, three is trio, two is duo (?) and one is solo. I see every number has different name. So:

1. What is the name for five?
2. Is there any language of this naming because a friend of mine said that "try Latin, I think it's the language".

also see "quinquennium" or "lustrum" – Elzo Valugi Jun 23 '14 at 13:16
And there's "quintuple" for a group of non-people. – reinierpost Jun 24 '14 at 8:39

The naming of groups does indeed come mostly from Latin, sometimes with Italian influence. The etyomologies for the first nine are:

```
Number    Group name     Latin      Italian      Meaning
1         solo         solus       solo        "alone"
2          duo           duo        due        "two" - this is the Latin word
3         trio          tres        tre        "three" - tres, but on the pattern of duo
4        quartet       quarto    quartetto     "fourth" (as opposed to "four")
5        quintet       quintus    quinto       "fifth"
6        sextet         sex        sei         "six" - from the Latin (old English: sestet)
7        septet        septem     sette        "seven"
8         octet         octo       otto        "eight"
9         nonet        novem       nove        "nine"
```

It is odd how 4 and 5 have their root in the ordinal number ("fourth, fifth") while the others count directly (two, three, six, etc). Also - the "-et" ending can have the connotation of "a piece written for..." (e.g. "duet").

I believe it's "O sole mio" where sole = sun. – James Jun 23 '14 at 3:17
@James - yes you are right. I shouldn't write answers at 2 am. What was I thinking- error removed. Thanks for pointing it out. – Floris Jun 23 '14 at 5:36
I like the way you answer it. Thank you for your complex answer :D – seseorang Jun 23 '14 at 16:22
The Italian table is all mixed up: if you wanted to write the names of the numbers they are: uno, due, tre, quattro, cinque, sei, sette, otto, nove. If you wanted to write the names of the groups they are: solo, duo, trio, quartetto, quintetto, sestetto, settetto, ottetto, nonetto. If you wanted to write ordinal numbers then they would be: primo, secondo, terzo, quarto, quinto, sesto, settimo, ottavo, nono. Your table mixes all these three elements. – Bakuriu Jun 24 '14 at 7:50
@Bakuriu - I am writing the etymology of each of the group names - sometimes these are numbers, sometimes ordinals, sometimes (as in "solo") neither. I am showing that most of the names can be traced to Latin, and that where the etymology is from the Italian, it's not always from a number. I am sorry if I did not make that clear - I do know how to count in Italian, but my point was (intended to be) that that doesn't always explain the names of the groups. Maybe I should make an additional column in my table - but then the description falls off the edge... – Floris Jun 24 '14 at 7:52

A quintet.

For example, the Miles Davis Quintet or the Charlie Parker Quintet with Dizzy Gillespie.

Johannes Brahms wrote a Piano Quintet in F minor, but no, it's not a piece for five pianos (it's for piano plus string quartet).

According to Merriam-Webster, the etymology of the word is Latin by way of Italian, from the Italian word "quintetto." First known use dates back to 1811.

It is a quintet.

A quintet is a group containing five members. It is commonly associated with musical groups, such as a string quintet, or a group of five singers, but can be applied to any situation where five similar or related objects are considered a single unit. In classical instrumental music, any additional instrument (such as a piano, clarinet, oboe, etc.) joined to the usual string quartet (two violins, a viola, and a cello), gives the resulting ensemble its name, such as "piano quintet", "clarinet quintet", etc. A piece of music written for such a group is similarly named.
