If the rhythm is started using the last position of the coup de 4 and the knob is pushed slightly further round, that gives the longer interval required.
Once the basic trompette techniques are second nature, variations in start position and subtle changes in style result in unlimited rhythmic possibilities.
I have found the following works well for Mazurka and for playing some pieces in 6/8.

The problem I had with Mazurka was the short coup between 3
and 4. This coup can be done by modifying the normal coup de 4 but it is
very difficult to smoothly play coups 3 and 4 using the base and joint of
the thumb.
If the rhythm is started using the last position of the coup de 4 and the knob is pushed slightly further round, that gives the longer interval required. |
|
The second coup is played with a downstroke of the thumb in the normal manner although the knob is further round than in the coup de 4. |
|
The third coup is done as in the coup de 4 but the knob is pulled slightly further round. |
|
The last stroke is then played with the 3rd and 4th fingers
as in the 3rd coup of the coup de 4 and ends in the normal position for
the 4th stroke of the coup de 4. As the previous coup was longer, the knob
has a shorter travel .

| In motion, it can be seen that the dotted rhythm of the mazurka falls quite naturally with this method. |  |
Think of a rectangle
