Part 4/11:
Biato delves into the intricacies of transposing instruments—clarinets, trumpets, French horns, and others. For example:
Clarinets (B flat): Sound a whole step below written pitch, requiring the notation to be transposed accordingly.
Trumpets (B flat): Also sound a whole step below, and often play in first inversion for the Star Wars opening, adding harmonic interest.
French horns (F instrument): Sound a perfect fifth below written pitch, demanding that to produce a B flat major chord, the horn plays an F major chord (F, A, C). These notes form the third and fifth of the B flat major chord, with the horns doubling the root at certain points to bolster the sound.
