Question 1 Report
[Listening extract audio not available in printed QP]
In the extract, the left hand plays broken chords in the pattern lowest-highest-middle-highest. What accompaniment is this pattern. [1]
The correct answer is Alberti bass. [1]
The Alberti bass is a specific pattern of broken-chord accompaniment in which the notes of a chord are played in the order: lowest, highest, middle, highest. For example, in a C major chord, the pattern would be C-G-E-G, repeated continuously. This creates a gently flowing accompaniment that fills out the harmony without overwhelming the melody above. The Alberti bass is named after the Italian composer Domenico Alberti (c. 1710-1740), who used it extensively. Although it originated in the late Baroque period, it became one of the most characteristic accompaniment patterns of the Classical period, appearing frequently in keyboard sonatas by Mozart and Haydn. It is particularly effective in creating a sense of forward motion and harmonic fullness with a simple left-hand pattern.
