Counterpoint - No. Of Leading Tones In The Cantus Firmus

The problem is most likely the tritone (otherwise called the diablo en musica) that you have created from having the B and F play at the same time. That breaks a major rule in counterpoint. In fact, you do it twice. Furthermore, the fourth that you create with those notes are considered "dissonances" so you'll need to change the interval to a consonant one (3rd, 6th, 8th, or 5th). The fourths you have seem to be a consistent problem.

Alex, I don't believe there is a rule that you can only use the leading tone (in this case b) once, but perhaps you can only use the leading tone as that function. In other words, Rbarate, you can use 2 b's in the cantus firmus, but the function as a leading tone may only be used once at the end.

I'm using Sibelius and if I use a B in the middle of a Cantus Firmus he says there are two (or more) leading tones as if it is an error.

By other hand, if I don't resolve it to C, it creates another error. I couldn't find any information restricting the use of more than one leading tone but I also couldn't find any example of its application. :whistling:

This might be because the using the F and B at the same time creates sort of a leading to C major. If you use it the way that Alexander used it earlier, it should be fine.
