LESSON 1 BINARY & TERNARY FORM Ø There are three types of binary forms, rounded binary, balanced binary, and simple binary. They all consist of two parts, with both parts normally repeated and ending with a cadence. This image is an example of a melody written in binary form It begins in A minor in the A section., and modulates in the B section to C major, the related major key. https://phamoxmusic.com/wp-content/uploads/2021/01/Binary-Form-Bourre-by-bach.jpg Ø The rounded binary form begins with a repeated A section, followed by a contrasting B section, which comes before the reinstated section A that is sometimes varied. The beginning of section A normally starts on the tonic and ends in the tonic Key that could be a half cadence. The B section can begin in a key other than the tonic or employ other techniques to emphasize the contrast. The return of section A takes place in the tonic key and ends with a cadence in the home key. In this image of the bin...
ENTRY 8 Figured Bass and Lead-Sheet Symbols * Triads can be arranged in three positions and these are called root position, first inversion and second inversion. These inversions can be identified in figured bass and lead-sheet with the use of various symbols. * Having a triad in root position, the root note is in the bass, for example, the C major triad, in root position the C would be the bass note with E and G above it. This is made up of a major third and a perfect fifth from the bass note. The symbol used in this inversion for figured bass is 5/3 and the lead-sheet, a capital C . * The first inversion would have the third degree of the triad in the bass, for example, using C major E would be in the bass with G and C above it. This is made up with a minor third and a minor sixth from the bass note. In this inversion, the figured bass used 6 or 6/3 and the lead-sheet used C/E. * In the second inversion, the fifth degree of the triad is in the bass with ...
LESSON 3 VARIATION FORM Ø Variation form is a musical idea repeated throughout the melody in different ways. Some of the ways that create a variation to the musical idea are its rhythmic pattern, ornamentation, and mode change. There are two primary types of various forms: continuous and sectional variations. This image of the Theme and Variation shows the theme below. Above are the variation, and the notes highlighted in red are the corresponding notes from the theme. http://www.raymelograne.com/uploads/5/8/3/0/5830182/4943018_orig.jpg Ø Continuous variation is a style developed throughout the Baroque period under two forms, the ground bass, also called passacaglia and chaconne. Ø Ground bass or passacaglia features a repetition in the bass line with its variation in the upper voice. At times, the upper voice takes on a portion of the bass line repetition that can be as long as a phrase and sometimes overlaps. In this image of Passacaglia, a...
