If its the G and the A I'm thinking about then it's 5th partial and would naturally be out of tune and flat.
Technically the G and the A are both flat on 5th partial - if the G is the 2nd line G in the treble? If its the octave above the G is 9th (open fingerings) and the A is 10th. The A would be somewhat flat with the G somewhat closer to being in tune. I'm not entirely sure what your question was but I hope that helps some? -William In a message dated 10/12/2005 4:41:27 P.M.

Our horn players (reformed vocalists ^_^) were having some trouble with fingerings, so we went over the harmonic series on the horn when we ran into an interesting phenomenon. I'm a horn player and so is the instructor, but niether of us knew the answer to this question. On the Bb side of the horn, we run into an out of tune harmonic on the A, so we go to the harmonic above to find a fingering that's in tune. But we still use the A to find the fingering for the G below that. If pressing down a valve (in the correct order) only lowers the pitch by a half-step, why is the G generally in tune when the A is not? I hope that question makes sense.
