- You would still be playing in the first octave by adjusting your fingers.

Revised Instructions:

1. Use the following fingerings for the main melody:

_Note_ | _Finger placement_

---------- | ----------------

D5 | T1 2 3 L12 RH3

E5 | T1 2 3 L12 RH1 RH3

F#5| T1 2 3 4 L12 RH3

E5, E5, E5, G5, G5

G5, G5, F#5, F#5, E5

E5, D5, D5, E5, E5

```

3. For the lower part:

- Use regular finger placement for the notes C5, D5, E5, and F5.

4. For the rising parts:

- Play A4, B4, and C5 using side key A, side key Bb, and side key C, respectively.

- Adjust your fingers to play D5, E5, and F5 for the rising notes at the end, similar to the main melody.

5. For the descending part:

- Play G4, F#4, and F4 using the side key G, side key F#, and side key F.

- Slide down to E4 and D4 as you would normally do.

Remember to practice slowly at first and gradually increase your speed and proficiency. If you find it challenging to use any of these fingerings, feel free to customize and adjust based on your comfort level and the fingering chart of your clarinet.
