next week I have to give a lecture on Rachmaninoff's B-minor moment musical for a school presentation. I will hopefully have aid of a keyboard so I can demonstrate certain things.
Here are the things I have found while analyzing the piece:
in measure 5 there is a plagel cadence
I don't see any cadence at all in measure 5. Are you counting the first beat as a measure? Because if there are not 4 beats in the bar, you can't count it as a separate measure.
I do see a cadence in measure 4, but it's not plagal, it's just a V
7/III to III, with a III pedal.
in measures 1-2 on page 2 the base notes of the triads make the main theme
Does everyone have the same edition as you? Why don't you just name bar numbers?
before climax no.1 there is another plagel cadence
I think I can tell what you are talking about, the climax in measure 26, and you should be more specific... but I don't see any plagal cadence. The chord that leads into m.26 is a V
7, but it is not a real cadence because the music keeps going. Even a few bars before m.26, there's no plagal cadence!
in the qausi-march section there is a harmonic pattern. This is whenever there is a triad he gives it an inversion, whenever there is a third he brings the top note down an octave to make it a sixth. on chords 1 and 2 of measure 4 (chord no.1 can be considered a G-Major chord with an F#-A third or a B-minor chord with a g-a ninth and chord no.2 could be considered a diminished C-Sharp minor chord with a g-a second or an A-Major cohrd with a G octave) are revealed as a B-minor chord (this time with an A) and chord no.2 is revealed as a diminished C-Sharp minor chord.
I don't understand this at all. What do you mean, "whenever there is a triad he gives it an inversion?" Do you mean, that triads first come in one form, then in inversion? Or do you mean, more simply, that the melody is written in parallel sixths. This is also called "faux bourdon."
What is measure 4? Where do you start counting in the "quasi march" section? It's not clear at all. Just give general measure numbers for the whole piece. I really don't see these chords you are describing. A G major chord with F# and A would be a G major 9th chord. As for diminished, there are no "major" or "minor" diminished chords, there are only diminished chords (or half-diminished). So you mean, a diminished chord on C#? Or an A 7? That's totally confusing.
on measure one of bar one of page no.3, the climax on page 2 is repeated except this time in E-Minor.
Bars don't have measures, bars are measures. Do you mean "measure one of [line] one"?
What edition do you have? Do you have an edition where the second fortissimo is on the top of the page? That would mean the page would only have 10 bars, that doesn't sound likely.
one measure 2 of the final bar there is a deceptive cadence.
Do you mean, "[on] measure 2 of the final [line]"? In any case, I don't see a deceptive cadence.
the developement that lead to the march theme one page two is repeated except in E-Minor like the recapitulation of the climax
That's actually an important point - but you should always tell the people why. It goes to show, that Rachmaninoff does not waste any material. Even a short transition is used again, this time to close the piece.
See what I mean? Generalize, generalize, generalize. These things that one points out in music have to go towards describing a larger point; the fact that he uses the same material in itself is not interesting.
It ends on the sub-dominate harmony with a single that is a D.
Yikes. This piece ends in b minor; there is a suspended E which resolves (4-3), but there is no ending on a sub-dominant.
Back to the books!
