There are 2 main types of sequence you will come across in music: Melodic Sequence – This is the repetition of a melody (like in the above example) Harmonic Sequence – This is a repetition of a series of chords (I will explain this later) When the word “sequence” is used it generally implies that both melodic and harmonic material is being used.

In music, a sequence occurs when a musical pattern is established then repeated at various transpositions. Sequences can be any combination of the following categories: melodic, harmonic, or both ascending or descending diatonic or chromatic single or multiple parts within each repeated segment

The function and impact of sequences in music composition Tonal sequence: staying within a key Real sequence: exact transposition of notes Mixed sequence: a combination of tonal and real Harmonic sequences: building chord progressions Descending thirds sequence Ascending harmonic sequences Ascending circle-of-fifths sequence

By creating harmonic and tonal variety with a unified pattern, the sequence serves as a means of musical development. Two types of sequence are commonly used: nonmodulating (or tonal) sequence, which keeps the restatements all in a single key; and modulating sequence, which may traverse several keys.

There are two main types of sequence in music: melodic sequence and harmonic sequence. Usually, a sequence contains both melodic and harmonic material.
