defined sequence: a musical pattern restated immediately at different pitch levels (transposed), with transposition happening at a consistent interval

            melodic sequence: the melodic pattern is restated (often just one voice/hand/instrument)

            harmonic sequence: the harmonic pattern restated (have to look at harmonies)

            (often the two are combined)

            often combined with a linear intervallic pattern (LIP) a consistent pattern between soprano and bass voices

 

            how to label?

the first statement is the model

            subsequent statements are the sequence or copy [different from text]

 

            diatonic sequence: stay in the same key as you transpose the model (so no accidentals; intervals between notes/harmonies might change)

            chromatic sequence: change keys as you transpose the model (so will have accidentals)

 

show an example of melodic sequence in the Invention: mm.7-10 RH is one example, where the original model is transposed down a step

 

            can they find another one? (mm.11-14 LH)

 

            why are opening 7 mm not a sequence? (b/c simply 8ve transposition)

 

then show an example of harmonic sequence: m7-11

            -what would these harmonies be if we put them in root position and wrote them out?

            (D minor chord, G minor chord, C major chord, F major chord)

            -to figure out the pattern, we look at the ROOTS of the harmonies: D-G-C-F

            -if put in a long line, what do you notice? (descending 5ths)

            -this is the most typical sequence type

 

-harmonies are grouped in 2s to form this harmonic sequence: that is, there are 2 harmonies per melodic sequence

-notice that the bass line doesn't necessarily show the descending fifths: instead you might think it's descending second, because the melodic sequence is transposed down a step

-so, here's the trick: to find the melodic interval of transposition, look at the melody and how it's transposed

but to find the harmonic sequence, consider root motion of the harmonies

 

-circle the roots

-bracket the model and sequence/copies

-now, what inversion are the harmonies? all root position

 

Now you do it (from handout)

            -look at Paganini example in groups, then show answer

 

students do the rest of the handout
