Not all duets are corny. Some duets can actually be quite artistic and creative. Walking the Narrow Path does not play out like a typical duet. It was conceived as a light performance piece. The rhythms are dreamy and the melodies are almost hypnotic.
The piece is in odd meter, which is fun for the musicians and interesting for the audiences. The top note in the first part is a B flat above the staff, which is not high, but the part stays high long enough to be an endurance challenge.
The skill level is intermediate/advanced. If you are familiar with Eddie Lewis’ seven levels of difficulty, this composition is at the Trumpet Pro level in his system. This is mostly because of the range and the odd meter time signatures.
