Hiii,,,
I'm doing a presentation/speech for a class where I plan to have a piano up there with me (a portable 3 octave one) so I can walk people through time with famous piano composers, and show them about each style. It's not a music related class (its a public speaking class) so it can be very surface level content. I also only have 8 minutes so has to be VERY brief considering the scale of the topic.

Here's what I'm thinking so far:

Baroque era, Bach:

Talk about how the piano was just being invented around this time no sustain pedal, play a bit from a fugue perhaps and talk about how he used different voices (is that a good representative quality of the keyboard music of that period?)

Classical, Mozart and Beethoven:

Mozart introduced the sonata form, started using repetition, play a bit from maybe K545 M.1 or Rondo Alla Turca

What is most characteristic of Beethoven? Big, strong chords? Gradual build-ups to big, urgent-sounding moments? (was he the first one to popularize this style that chopin and liszt employed as well?) Could use a hand with this one
Romantic, Chopin and Liszt:

Chopin introduced rubato, lots of pedal, play a the opening melody of Nocturne op.9 no.2 to demonstrate rubato

Liszt turned the piano in to a solo performance instrument, known for technical difficulty

Modern era, maybe Debussy and Gershwin? Rachmaninoff, Joplin?

Maybe a little bit about jazz and how it loosely relates to the above content

And if possible, some way to relate this all back to the music we hear today and why this was all so important



Any help would be GREATLY appreciated, thanks so much! Or if I can be directed to some great resource or video covering a similar topic (vinheteiro sort of does this but with no explanations)....
Thanks,...
