Staff Notation: Clefs and Key Signatures


The excerpt - in 3/4 meter - shown above is obviously for 3 instruments. The top line repeats a 1-measure motive, while the voice notated on the middle staff moves along in a continuous dotted rhythm. The lowest instrument plays a two-measure figure punctuated by a quarter rest.

For your consideration: 1] What are the clefs and key signature of the excerpt? 2] Where during the course of the 6-measures do complete triads occur on the beat? incomplete ones? 3] What is the significance of the chromaticism?

I am most interested in finding out different musicians’ methodologies in deriving the solution, so do write me a comment explaining your rationale if you have a moment.

It appears that the key signature would be 2 flats (Bb Major), both because that's logical based on how the excerpt would sound and as an explanation for the E-naturals (the Eb in the pickups to the first measure of the excerpt cancels out a natural that must have been at the beginning of the "pickup" measure).

I'm going to guess that the clef of the uppermost voice is treble, the middle voice is treble with octava basso (or failing that, which I don't think I've ever seen except in vocal parts, regular treble), and the bottom voice is in bass clef.

The chromaticism, such as it is, consists simply of leading tones to the dominant, F.
