My advice would be to try composing/improvising some short melodies and then experiment with repeating them at different transpositions. Have a look/listen to the following example of a sequence: There are 2 main types of sequence you will come across in music: When the word “sequence” is used it generally implies that both melodic and harmonic material is being used. The interval sequence of the harmonic series is always the same. The Oxford Dictionary of Music defines a sequence as the “more or less exact repetition of a passage at a higher or lower level of pitch”. These changes in quality continue through all 4 bars of the sequence and so our sequence example is a Tonal Sequence. He is a music teacher, examiner, composer and pianist with over twenty years experience in music education. 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 materialis being used. on Google+, Ben Dunnett LRSM is the founder of Music Theory Academy. I am going to explain sequences in music by showing/playing you various examples. Descending fifths sequences, also known as "circle of fifths" sequences, are the most commonly used types of sequences, singular extended in some works of Claudio Monteverdi and Heinrich Schütz. As always, if you have any questions, please feel free to contact me. For example, the interval from the 2nd to the 3rd harmonic is always a fifth. I hope you have found this lesson on sequences helpful. (Kennedy, M.). The intervals depend only on the position in the row. However, the interval qualities change (major 3rd, minor 3rd, major 2nd, minor 2nd in the first melody become minor 3rd, major 3rd, major 2nd, major 2nd in the repeated melody): It usually consists of a series of chords whose bass or "root" notes follow a pattern of descending fifths (or ascending fourths). The full sequence would look and sound like this: A sequence that has several repetitions, some of which are tonal and some of which are real is called a Mixed Sequence. A sequence is where a passage of music is repeated at a higher or lower level of pitch.

Harmonic sequences abound throughout musical history—they are a logical and satisfying method for spinning out a musical idea. Its name derives from the concept of overtones, or harmonics in music: the wavelengths of the overtones of a vibrating string are 1 / 2, 1 / 3, 1 / 4, etc., of the string's fundamental wavelength. There are 2 main types of sequence you will come across in music: 1. The repeat can be an exact transposition – a real sequence or the intervals can be changed – a tonal sequence. Regardless of which tone you start with, the series results always in the same melody … Thank you for subscribing. However, the interval quality changes (e.g. Every term of the series after the first is the harmonic mean of the neighboring terms; the phrase harmonic mean likewise derives from music. This sequence gets its name from the fact that each successive chord has a root note that is a fifth lower than the previous chord. on Facebook Subscribe to our mailing list and get FREE music resources to your email inbox. Share this post: In an ascending circle-of-fifths sequence each chord’s root is a 5th higher than the previous chord in the sequence. 4th, 5th, etc..). Have a look/listen to this piano piece I wrote called “A Time To Mourn”. Melodic Sequence – This is the repetition of a melody (like in the above example) 2. You can see how we have converted the 2 “F” notes to “F sharp” notes so that the interval qualities remain the same. If we convert our example of a sequence into a real sequence it would look as follows: a minor interval may become a major interval) This change in quality is inevitable if the composer wants the key to remain unchanged. In a real sequence there is no change in either the size or quality of the intervals (this will usually mean that the composer has to change the key as the sequence progresses). In a tonal sequence the intervals between the notes are altered to some extent. In a descending thirds sequence the chords move down a third for each repetition, hence the name. The piece shows clear examples of melodic and harmonic sequences (I have annotated the sheet music to show the sequences). In our example of a sequence you can see that the interval sizes remain the same across the 2 melodies (3rd, 3rd, 2nd, 2nd in the 1st melody stay as 3rd, 3rd, 2nd, 2nd in the repeated melody): I am sure that you will be pleasantly surprised by what you discover! info)), respectively.

Read More. The interval size usually stays the same (i.e. Sequences are an excellent tool for composing music – I use them in a lot of the pieces I write. The just minor third appears between harmonics 5 and 6 while the just fifth appears lower, between harmonics 2 and 3. on Twitter After observing these examples from Bach, you will have many opportunities to discover them in the music of later periods.
