How do we actually create musical textures? There are several strategies that composers like to use.
The first textural device we can use appears in the bass line. There are two common bass lines: Alberti bass and walking bass.
Alberti bass consists of a repeating arpeggio pattern that moves in a continuous, rolling motion. It is typically played on a keyboard instrument, such as a piano or harpsichord, and is used to provide a sustained and harmonically rich accompaniment to a melody. The pattern is usually played in the left hand while the right hand plays the melody.
The standard Alberti bass pattern consists of a broken chord in which the notes are played in a descending order, starting with the root of the chord, then the fifth, then the third, and finally the root again. The pattern then repeats, starting on the next chord in the progression. This creates a smooth, flowing accompaniment that can provide a sense of forward momentum and momentum to a piece of music.
