My Arban`s says to double-tongue by prononcing the syllables "tu" and "ku" alternately. To pronouce "tu" without the trumpet I put my tongue against the bottom of my upper teeth momentarily. To pronouce "ku" without the trumpet I don`t seem to use my tongue at all, so I don`t see how this can be a tonguing. Pronouncing "ku" with the trumpet I can`t get any sound at all. What am I missing here?

He wants to know how to double tongue. I`d be interested in an answer to his query.

Re: "He wants to know how to double tongue. I`d be interested in an answer to his query."

As would I. It seems to me a pretty basic trumpet question.

The syllable `tu` is pronounced with the tip of your tongue striking the back of your upper teeth.

The syllable `ku` is pronounced with the back "arched part" of your tongue striking the very back of the roof of your mouth.

It feels awkward to double tongue like this at first, but with practice you can get two notes in rapid succession.

I can`t get a sound at all, even in slow non-succession.

Re: ""The syllable `ku` is pronounced with the back `arched part` of your tongue striking the very back of the roof of your mouth."

Since the "very back of the roof of [my] mouth" is nowhere the trumpet mouthpiece, I don`t understand how this is supposed to constitute an attack, to initiate a tone.

To get a feel for what I am saying...begin by just playing a very easy going open `G`. Then very easily without trying to double tongue yet, make the sound `ku`. Even though the tongue itself is not near the nouthpiece, it can still interrupt the flow of air.

Try thinking about a garden hose with water coming out. The taking your hand and waving it back and forth in front of the spout. You are not actually stopping the water, just interrupting the flow.

I know it feels awkward at first, but you will see that the `ku` sound will eventually get you the desired result. After you can do the `ku`, then try the `tu-ku`
