What is the technical name for this rhythm?

This has been annoying me for several days now. The rhythm I've forgotten the name of is a dotted note followed by two notes that are relatively much shorter. For example a dotted crotchet followed by two semiquavers. I've demonstrated what I mean in the attached PDF. Any help please? Thanks a lot guys :)

Didn't know it had a name.

But what you did in your file was rhythmic diminution. The reduction of the size of note value by a specific ratio. I.e. half, 2 8ths becomes quarter, 2 16ths at a ratio of 2:1.

The rhythm I've forgotten the name of is a dotted note followed by two notes that are relatively much shorter.

...name? What are you talking about? Like what?

I believe the word you're looking for is "Avian Cortège."

JK. I didn't know that had a name. You can try Avian Cortège in a dictionary though....

lets see dotted half-note, 2 8th notes(quaver). then dotted quarter(crochet) note, 2 16th notes(semiquavers).

then dotted 8th note followed by 2 32th notes(demisemiquaver)?

you mean the gradual increase in tempo that flows over this phrase?

Trill with identity issues

Thanks for the responses guys! The name actually came to me in a divine flash of inspiration last night.. Its called a declamatory rhythm. Nothing to do with diminuition, I just used different, shortening note values to demonstrate what I meant, and I lol'd at the trill with identity issues :D Thanks fellas! ^.^

years ago I was part of an Mexican Ethnic group, and some rhythms have names, I recall the "salla", the "Takirari" and others.... but if we name each rhythm we can create, we would need millions of words.

One of my teachers calls it "double speed" and "double slow"

Why? I don't know.
