Typically the F attachment provides alternate positions for low C and B natural, as well as extending the range below the lowest E. Many trombonists are not aware of one of the most important F attachment alternates: the low Bb in v-3 (significantly lowered third position, usually below the bell). Here you will be able to spot all the notes that can be played on more than one slide position as well as the slight adjustments needed for certain notes on certain positions.

Looking at for example above with the G major triad played in 4th position, I suggest that on the trombone, you should hold the third (B) up a bit and the 5th (G) slightly down – the opposite of the best practice for triads. Note that many of the notes could be played with alternate positions as well, but this is the most common solution. The seventh partial should not be playedbecause it is too flat.
