The opening of the last movement of Haydn's 104th symphony
Jonny opening
Shows the relationship between the simple melodies and harmonies that the music is often based on and the folk music that would have been common at the time
The exact relationship between the Jonny opening and the Croatian folk music is lost in the mists of time
Haydn knew the Jonny opening as a folk melody or thought of it as a folk melody
Jonny opening
Starts off very simple over a drone, as it may well be in its original setting and with no other real accompaniment apart from that drone
Although the material is accessible and simple and folk-like, what Haydn does with it over the course of the movement is incredibly sophisticated
The pairing of accessibility and simplicity with complexity and sophistication is the hallmark of the mature Classical period and particularly the hallmark of composers like Haydn
Sonata form
An art form with an exposition, development, and recapitulation
The last movement of Haydn's 104th symphony is in monothematic Sonata form
Monothematic Sonata form
The first subject (S1) is used again for the second subject (S2)
Haydn makes more effort to differentiate the two subjects compared to the first movement
Ways Haydn differentiates the first and second subjects
Includes a more prominent counter-melody in the second subject
Includes a second second subject (S2b) that contrasts with the main second subject
Interrupted cadence in bar 83
Delays the final arrival on the dominant for the coda at the end of the exposition
At the end of the development section
Haydn is in the wrong key (F-sharp minor) instead of the expected dominant of the home key (D major)
Haydn's use of interrupted cadences
Messes with the listener's expectations
Motivic and thematic aspects
Haydn uses motifs intensively, tracing the development of one particular motif (Y) throughout the movement
The Y motif starts as a quiet counter-melody, becomes more prominent, and is eventually transformed into a confident, rising melody in the full woodwinds
There is so much going on in this movement that several videos could be filled with the details
