Although Sor composed numerous pieces for the guitar, I will limit my focus to two of them, each of which showcases notable aspects of Sor’s compositional style. Because Sor composed in a wide range of forms both large and small, including studies, waltzes, theme and variations, divertimentos, and sonatas, I have chosen to briefly analyze one of his studies and one of his works that uses a larger form. For the former, I will discuss his Study No. 8, Op. 6, focusing on its use of multiple voices, suspensions, and part-writing. For the latter, I will explore his Introduction and Variations on a Theme by Mozart, Op. 9, with emphasis on its virtuosity, connection to Mozart, and role in elevating the status of the guitar.
The music of Sor is typically introduced to guitar students through the many studies that Sor composed. These studies have stood the test of time for their technical and musical appeal, and, along with the pedagogical works of Carcassi, Carulli, Giuliani, and Aguado, make up a large portion of today’s typical classical guitar curriculum as taught in private lessons and university courses. Sor’s Study No. 8, Op. 6 is among his most popular studies, and showcases his part-writing ability, as well as his use of both vertical and horizontal compositional styles. This study was first published in 1815 in London, and is dedicated to his pupils, further evidence that it was intended as a pedagogical work. Despite its short length of thirty-nine measures, the study features three independent voices, suspensions, grace notes, and several key changes. It is comprised of five short sections (referred to by Stanley Yates as “episodes”) and is through-composed. Each voice has an independent part, illustrating Sor’s polyphonic approach to composing for guitar, as well as his deft use of suspensions, which can be seen in the following excerpt of the first four measures:
By contrast, his Introduction and Variations on a Theme by Mozart, Op. 9 is a significantly longer and more technically demanding piece. The theme is based on the melody of “O Cara Armonia” a theme from The Magic Flute, one of Mozart’s most famous operas. There are several stylistic similarities in the music of Sor and Mozart, including the use of forms common during the classical period, and their penchant for clear phrases and lyrical melodies. In addition, the use of a theme by Mozart appears to imply Sor’s acknowledgement of his influence.
This piece also showcases the prodigious capabilities of the guitar, especially in the variations, which incorporate great technical skill and musical imagination, both of which assisted in raising the status of the guitar. As Graham Wade notes in his book Traditions of the Classical Guitar: “there are no precedents in guitar literature for this tour de force in which all the technical devices of the guitar are developed with such gusto.” It was first published in Paris by A. Meissonnier in 1821, and achieved a renaissance in popularity in the mid-twentieth century when Andrés Segovia chose this piece as the first work by Sor that he recorded and performed. Segovia’s popularization of this piece led to its current reputation as a rite of passage for aspiring classical guitarists. Its form consists of a short introduction, which is followed by the theme, five variations, and a coda. Each variation utilizes different variation techniques, including change of key, change of mode, embellishment of melody, change of harmony, and unique rhythmic figure, as well as many passages featuring rapidly played scales and arpeggios. In my brief discussion of these variations, I will show the first two measures of the theme and each variation, noting some of the variation techniques that I have discovered in my analysis of this work:
Variation 1 (slurs, 32nd notes, and scale run embellish the theme):
Variation 2 (Change of mode (parallel minor) and change of harmony):
Variation 3 (Rhythmic variation: straight sixteenth notes and arpeggio in measure 1 of this variation):
Variation 4 (Unique rhythmic figure, arpeggiated chords):
Variation 5 (Different unique rhythmic figure and sequences):
