This app, designed to help you practise double tonguing for Trumpet and Cornet, is available for iPhone and iPad from the App Store and for Android Phone and Tablet from Google Play and you can view a demo video  on our site’s Trumpet page.

First of all here are some important general tips about developing your double tonguing for Trumpet and Cornet.

• The better you single tongue the better your double tonguing will be.
• If you can single tongue a passage with clarity and control don’t double tongue it.
• Aim to get your double tonguing to sound as crisp as single tonguing.

The app helps you practise ten exercises for double tonguing for Trumpet and Content from the Arban Complete Method and each one of them at sixteen different speeds.

Below is an example of how you could practise Ex, 77.

Firstly, try single tonguing at Tempo 50bmp. In other words by start at a slow tempo.  Then with the ‘sound’ of the crisp single tongue in our head try to get the double tongue (ku) equally as crisp as the conventionally tongued tu. Also make sure you keep in time.
If you find it difficult to go all the way to F just stop where you need to and start again from the beginning. Eventually your muscles will develop the strength to reach the higher notes.
DO NOT force the sound out by using too much pressure or altering the shape of your embouchure!

Now try it at 60 bpm:

Here’s another way to use the app.
There is a temptation to use double tonguing too soon, at speeds which would be better single tongued. It is therefore very useful to use use these exercises to quicken your single tonguing technique as well as your Double Tonguing.
When you get the app you could test yourself on how quickly you can single tongue. You should aim for perhaps 100/ 110 semiquavers (16th Notes).
