I am composing a bagatelle and it is turning out to be sort of a hybrid between your typical bagatelle and a sonata. However, even once the piece is finished, it would be too short for me to put Sonata in the title(5 minutes at most, that isn't long enough for an entire sonata). I mean, I guess I could call it the Sonata Bagatelle but then the title would be confusing.
Here is how I was planning things out.
I was planning to do it in rondo form. At first I thought of sticking to ABACA such as in Fur Elise. But the rondo form quickly expanded to be ABACABA, the typical form of a rondo in a sonata. But I was still planning on having 2 sections in the tonic. That is, until my melodic improvisation lead me somewhere else. This is really when the hybridization of the typical bagatelle and the sonata started happening. And it is why I am asking this question relating to bagatelles and sonata form.
I will show both the general terms and the Sonata Form terms here.
Here is the First Theme/A section of my bagatelle:
And here is its motive division:
As you can see, I have a lot of motives here. This means that I can have an extensive development without it being boring or completely unrelated sounding. Here are the motives:
- Red - Starting motive and its inversion
- Green - Second motive
- Blue - Triplet motive
- Purple - Dominant motive
- Orange - Scale motive
- Dark red - Cadential motive
Here is my Second Theme/B section:
And here is its motive division:
As you can see, I have a single motive here, a scale step that descends through the theme. This means that the Second Theme/B section can't contribute as much to the Development/C section as the First Theme/A section can, but it is pretty typical for 1 theme to have more motives than another theme in a sonata form piece.
With this, my bagatelle "Exposition" is in this form:
ABA
The C section, I am planning on having be in the parallel minor. So since I am in C major here, the C section would be in C minor. Here is my question.
Can bagatelles be in Sonata Form? Because that seems to be what my bagatelle is heading towards is Sonata Form.
