This project asks us to create two short pieces using imitative counterpoint. I wrote the first for vibraphone and tenor sax:
The first two bars of the tenor sax line are imitated by the vibraphone a bar later, and there are other shorter examples of imitation throughout the piece, e.g. in bars 5 and 6 both of the lines repeat their own melody a tone higher. I also used diminution in bars 7 and 8 of the vibraphone line (imitating the saxaphone line from bars 5 and 6). This mechanism seems to be good at building towards a climax as it naturally speeds up the melodic line.
My second example is for oboe and bassoon:
In this piece I have used straightforward imitation, inversion and augmentation. Bars 1 and 2 are imitated by the oboe in bars 3 and 4 (a sixth higher), and at the same time the bassoon plays an inverted copy. I also used imitation where the subjects start in close succession to each other, e.g. in the scale passage in bars 7 – 9 and at the very end. The augmented imitation is in the bassoon line in bars 11-14 (imitating the oboe’s melody from bars 11-12); it adds a serious quality to the music as it is stating the melody in long, deliberate notes.
Of the two examples I like the second one better overall as I think it has more creative merit. I do however really like the sound and agility of the vibraphone in the first one and would like to explore this further in future compositions.
