Adobe audition's spectral view might be worth a try. The notes should stand out as blobs of pitched stuff against the winding noise...select noise with marquee tool, then apply amplify effect set to minus something db....or alternatively, use the marquee tool to cut the melody out and paste it to a new waveform, leaving the winding noise behind. Really depends on the sample though, if they're mixed together at the same frequency or have overlapping harmonics there may not be much that can be done in that way.
