In music, a trio (from the Italian) is any of the following:
- a composition for three performers or three musical parts
- in larger works, the middle section of a ternary form (so named because of the 17th-century practice of scoring the contrasting second or middle dance appearing between two statements of a principal dance for three instruments)
- an ensemble of three instruments or voices performing trio compositions.
Composition
[edit]A trio is a composition for three performers or musical parts. Works include Baroque trio sonatas, choral works for three parts, and works for three instruments such as string trios.
In the trio sonata, a popular genre of the 17th and early 18th century, two melodic instruments are accompanied by a basso continuo, making three parts in all. But because the basso continuo is usually played by two instruments (typically a cello or bass viol and a keyboard instrument such as the harpsichord), performances of trio sonatas typically involve four musicians. However, there are also examples for a single performer such as Bach's Organ Sonatas or Trios, BWV 525â30 for two hands and a pair of feet, and also for two performers, such as his Violin Sonatas, Viol Sonatas and Flute Sonata, in which the harpsichordist's right hand performs a melodic part.
In vocal music with or without accompaniment, the term terzet is sometimes preferred to "trio".[1]
Form
[edit]From the 17th century onward, trio has been used to describe a contrasting second or middle dance appearing between two statements of a principal dance, such as a minuet or bourrée. This second dance was originally called a trio because of the 17th-century practice of scoring it for three instruments, and later examples continued to be referred to as trios, even when they involved a larger number of parts.[2] The Menuet of Bach's Brandenburg Concerto No. 1 (1721) is a late nod to the original practice, with trios for two oboes and bassoon as well as two horns and a third part played by three oboes in unison. 19th-century forms derived from the minuet, such as the scherzo, also often contain contrasting trios. It usually has a lighter texture than the principal statement of the dance or march.[3]
The term is also used for the contrasting section of a march, the middle section in a march with da capo or the final section of one without. March trios in major typically modulate to the subdominant of the principal key.
Ensemble
[edit]Derived from the compositions, trio often denotes a group of three solo instruments or voices.[2] The most common types of such compositions are the piano trio of typically piano, violin and cello, and the string trio of commonly violin, viola and cello.[4]
Other types of trio include [citation needed]:
- Brass trio (horn, trumpet, trombone)
- Clarinet-cello-piano trio (clarinet, cello, piano)
- Clarinet-viola-piano trio (clarinet, viola, piano)
- Clarinet-violin-piano trio (clarinet, violin, piano)
- Flute, viola and harp (flute, viola, harp)
- Harmonica trio (chromatic harmonica, bass harmonica, chord harmonica)
- Horn trio (valved or natural horn, violin, and piano)
- Jazz trio (piano or guitar, acoustic bass or bass guitar, drum kit)
- Organ trio (Hammond organ, drummer, jazz guitarist or saxophone)
- Power trio (electric guitar, bass guitar, drum kit)
