It is written using a grace note (often a quaver, or eighth note), with an oblique stroke through the stem. In the 19th century, the acciaccatura (sometimes called short appoggiatura) came to be a shorter variant of the long appoggiatura, where the delay of the principal note is quick. Hence the German translation Zusammenschlag (together-stroke). In the 18th century, it was an ornament applied to any of the main notes of arpeggiated chords, either a tone or semitone below the chord tone, struck simultaneously with it and then immediately released. The word acciaccatura ( UK: / ə ˌ tʃ æ k ə ˈ tj ʊər ə/, US: /- tʃ ɑː k ə-/ Italian: ) comes from the Italian verb acciaccare, "to crush". A lower inessential note may or may not be chromatically raised (that is, with a natural, a sharp, or even a double sharp) to make it one semitone lower than the principal note.Īudio playback is not supported in your browser. The same applies to trills, which in the Baroque and Classical periods would begin with the added, upper note. Mordents of all sorts might typically, in some periods, begin with an extra inessential note (the lesser, added note), rather than with the principal note as shown in the examples here. Although mordents are now thought of as a single alternation between notes, in the Baroque period a mordant may have sometimes been executed with more than one alternation between the indicated note and the note below, making it a sort of inverted trill. In the 19th century, however, the name mordent was generally applied to what is now called the upper mordent. In the Baroque period, a mordant (the German or Scottish equivalent of mordent) was what later came to be called an inverted mordent and what is now often called a lower mordent. Problems playing this file? See media help. Trilling on a single note is particularly idiomatic for the bowed strings. There is also a single tone trill variously called trillo or tremolo in late Renaissance and early Baroque. Such variations are often marked with a few grace notes following the note that bears the trill indication. Sometimes it is expected that the trill will end with a turn (by sounding the note below rather than the note above the principal note, immediately before the last sounding of the principal note), or some other variation. However, " Koch expressed no preference and observed that it was scarcely a matter of much importance whether the trill began one way or the other, since there was no audible difference after the initial note had been sounded." Clive Brown writes that "Despite three different ways of showing the trills, it seems likely that a trill beginning with the upper note and ending with a turn was envisaged in each case." In the late 18th century, when performers played a trill, it always started from the upper note. In Baroque music, the trill is sometimes indicated with a + (plus) sign above or below the note. Types Trill Īudio playback is not supported in your browser. In Spain, melodies ornamented upon repetition (" divisions") were called " diferencias", and can be traced back to 1538, when Luis de Narváez published the first collection of such music for the vihuela. Alternatively, the term may refer more generally to any of the small notes used to mark some other ornament (see § Appoggiatura below), or in association with some other ornament's indication (see § Trill below), regardless of the timing used in the execution. A grace note is a note written in smaller type, with or without a slash through it, to indicate that its note value does not count as part of the total time value of the bar. Frequently, a composer will have his or her own vocabulary of ornaments, which will be explained in a preface, much like a code. A number of standard ornaments (described below) are indicated with standard symbols in music notation, while other ornamentations may be appended to the score in small notes, or simply written out normally as fully sized notes. Ornamentation may also be indicated by the composer.
Similarly, a harpsichord player performing a simple melodic line was expected to be able to improvise harmonically and stylistically appropriate trills, mordents (upper or lower) and appoggiaturas. A singer performing a da capo aria, for instance, would sing the melody relatively unornamented the first time and decorate it with additional flourishes and trills the second time. In the Baroque period, it was common for performers to improvise ornamentation on a given melodic line.
