kawafanboi hehehe ….. totally with you on that. That's what happens when they find a new 'toy' … eg. counterpoint, or even fast finger scale and/or arpegg etc exercises, and/or trills etc. They can go overboard with it.
I don't mind trills, but have a feeling that they had to use them in the older days because harpsi and clavcords etc didn't have the benefits of our huge sounds and amazing nuances in our digi and acoustic pianos these days. So they had to embellish in other ways to keep something rolling along. Although, in some cases, trilling (even long ones) strategically included in just the right spots can be elegant ….. beautiful. In moderation is good. It's when stuff is overdone, over the top, overplayed etc that probably leads to some staleness, rejection, withdrawal symptoms etc.
Oh geez …… we got heaps of mosquitoes sometimes over here. Our number one defense is an awesome time tested product ….. Aerogard. Awesome product. Even comes in odorless form these days. Keeps those mozzies right at bay. Also works excellently against 'sandflies' aka coastal/mangrove midges.
