George Frideric Handel in the context of "Messiah (Handel)"

In music, an aria (/ˈɑːriə/ , Italian: [ˈaːrja]; pl.: arie, Italian: [ˈaːrje]; arias in common usage; diminutive form: arietta, Italian: [aˈrjetta]; pl.: ariette; in English simply air) is a self-contained piece for one voice, with or without instrumental or orchestral accompaniment, normally part of a larger work.

The typical context for arias is opera, but vocal arias also feature in oratorios and cantatas, or they can be stand-alone concert arias. The term was originally used to refer to any expressive melody, usually, but not always, performed by a singer.

Baroque music (UK: /bəˈrɒk/ or US: /bəˈroʊk/) refers to the period or dominant style of Western classical music composed from about 1600 to 1750. The Baroque style followed the Renaissance period, and was followed in turn by the Classical period after a short transition (the galant style). The Baroque period is divided into three major phases: early, middle, and late. Overlapping in time, they are conventionally dated from 1580 to 1650, from 1630 to 1700, and from 1680 to 1750. Baroque music forms a major portion of the "classical music" canon, and continues to be widely studied, performed, and listened to. The term "baroque" comes from the Portuguese word barroco, meaning "misshapen pearl". Key composers of the Baroque era include Johann Sebastian Bach, George Frideric Handel, Henry Purcell, Antonio Vivaldi, Georg Philipp Telemann, Domenico Scarlatti, Claudio Monteverdi, Girolamo Frescobaldi, Alessandro Scarlatti, Jean-Baptiste Lully, Jean-Philippe Rameau, Arcangelo Corelli, François Couperin, Heinrich Schütz, Dieterich Buxtehude, and Heinrich Ignaz Franz Biber.

The Baroque saw the formalization of common-practice tonality, an approach to writing music in which a song or piece is written in a particular key; this type of harmony has continued to be used extensively in Western classical and popular music. During the Baroque era, professional musicians were expected to be accomplished improvisers of both solo melodic lines and accompaniment parts. Baroque concerts were typically accompanied by a basso continuo group (comprising chord-playing instrumentalists such as harpsichordists and lute players improvising chords from a figured bass part) while a group of bass instruments—viol, cello, double bass—played the bassline. A characteristic Baroque form was the dance suite. While the pieces in a dance suite were inspired by actual dance music, dance suites were designed purely for listening, not for accompanying dancers.

Ternary form, sometimes called song form, is a three-part musical form consisting of an opening section (A), a following section (B) and then a repetition of the first section (A). It is usually schematized as A–B–A. Prominent examples include the da capo aria "The trumpet shall sound" from Handel's Messiah, Chopin's Prelude in D-Flat Major "Raindrop", (Op. 28) and the opening chorus of Bach's St John Passion.

The Royal Opera House (ROH) is a theatre in Covent Garden, central London. The building is often referred to as simply Covent Garden, after a previous use of the site. The ROH is the main home of The Royal Opera, The Royal Ballet, and the Orchestra of the Royal Opera House, which are known collectively as the Royal Ballet and Opera.

The first theatre on the site, the Theatre Royal (1732), served primarily as a playhouse for the first hundred years of its history. In 1734, the first ballet was presented. A year later, the first season of operas, by George Frideric Handel, began. Many of his operas and oratorios were specifically written for Covent Garden and had their premieres there.

A march is a musical composition with a strong regular rhythm which in origin was expressly written for lockstep marching of soldiers. As a musical genre, it is a type of martial music, most frequently performed by a military band during parades.

March music pieces vary widely in mood, ranging from the emotional funeral march in Wagner's Götterdämmerung to the brisk Romantic marches of John Philip Sousa and the militaristic hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op. 91a by Jean Sibelius, and in the Dead March in Handel's Saul.

A concerto (/kənˈtʃɛərtoʊ/; plural concertos, or concerti from the Italian plural) is, from the late Baroque era, mostly understood as an instrumental composition, written for one or more soloists accompanied by an orchestra or other ensemble. The typical three-movement structure, a slow movement (e.g., lento or adagio) preceded and followed by fast movements (e.g., presto or allegro), became a standard from the early 18th century.

The concerto originated as a genre of vocal music in the late 16th century: the instrumental variant appeared around a century later, when Italians such as Giuseppe Torelli and Arcangelo Corelli started to publish their concertos. A few decades later, Venetian composers, such as Antonio Vivaldi, had written hundreds of violin concertos, while also producing solo concertos for other instruments such as a cello or a woodwind instrument, and concerti grossi for a group of soloists. The first keyboard concertos, such as George Frideric Handel's organ concertos and Johann Sebastian Bach's harpsichord concertos, were written around the same time.

Opera seria (Italian pronunciation: [ˈɔːpera ˈsɛːrja]; plural: opere serie; usually called dramma per musica or melodramma serio) is an Italian musical term which refers to the noble and "serious" style of Italian opera that predominated in Europe from the 1710s to about 1770. The term itself was rarely used at the time and only attained common usage once opera seria was becoming unfashionable and beginning to be viewed as something of a historical genre. The popular rival to opera seria was opera buffa, the 'comic' opera that took its cue from the improvisatory commedia dell'arte. An opera seria had a historical or Biblical subject, whereas an opera buffa had a contemporary subject.

Italian opera seria (invariably to Italian libretti) was produced not only in Italy but almost throughout Europe, and beyond (see Opera in Latin America, Opera in Cuba e. g.). Among the main centres in Europe were the court operas based in Warsaw (since 1628), Munich (founded in 1653), London (established in 1662), Vienna (firmly established 1709; first operatic representation: Il pomo d'oro, 1668), Dresden (since 1719) as well as other German residences, Saint Petersburg (Italian opera reached Russia in 1731, first opera venues followed c. 1742), Madrid (see Spanish opera), and Lisbon. Opera seria was less popular in France, where the national genre of French opera (or tragédie en musique) was preferred.

"Lascia ch'io pianga" (Italian: [ˈlaʃʃa ˈkiːo ˈpjaŋɡa]; English: "Let Me Weep"), originally "Lascia la spina, cogli la rosa" (Italian: [ˈlaʃʃa la ˈspiːna ˈkɔʎʎi la ˈrɔːza]; English: "Leave the Thorn, Take the Rose"), is an Italian-language soprano aria by composer George Frideric Handel that has become a popular concert piece.
