What we can learn from Amy Beach’s Four Sketches, Op. 15 No. 1: In Autumn (1892)
In this blog post, I'll discuss the first movement, In Autumn. The clash between F# minor and A major, finally assuaged by the ultimate shift to F# major in the final measures, provides a great opportunity for hermeneutic analysis as it relates to the poetic incipit from Alphonse de Lamartine's L’automne. The opening parallel progressive period (F# minor to A major) features sentence structure, and two common-tone augmented sixth chords (Ger+6, measures 4 and 10; Example 1).
Another German chord, in measure 8, occurs in the predominant area and is achieved via harmonization of a 4 - #4 - 5 bass line (Example 2). The cadential extension of the second sentence features rich embellishments, including accented ornamental dissonances.
The contrasting B section (measure 39) begins with a brief tonicization of the Neapolitan (Example 3). The opening phrase (measures 39 - 46) has characteristics of sentence structure, and concludes with a PAC.
After embellished repetition of this phrase (as in the first period), transitional material based on motives from the A section lead to a pedal on C# (trill) in measures 61 - 62. While this trill is originally heard as the mediant, the deceptive motion in the following elided cadence (E7 chord to the F# minor relaunch of the A section, measure 63) reinterprets it as the dominant scale degree. The A section is harmonically altered upon its return. Where the original progressive period began in F# minor and modulated to A major, the second sentence of this later period begins in the parallel major after rapidly descending chromatic sixteenth-notes embellish a C# dominant seventh. The PAC in F# major at the end of this progressive period is elided with the reprise of the B section in the same key (elided cadence, Example 4).
The reprise of B and subsequent codetta feature heavy embellishment and ornamentation (including a tonic pedal, chromatic neighbor tones and incomplete neighbor tones, chromatic accented passing tones, upward-resolving suspensions/retardations) and chromatic harmony (secondary dominants and modal mixture). The penultimate chord is a common-tone Ger+6.
This is just a sample of some of the valuable information in this set of pieces. In Autumn is a great piece for analysis, and contains excellent examples of chromatic chords, cadences, phrase and periodic structures, motivic development, and contrapuntal use of dissonance.
