A half-wave, like a jumprope, doesn't get you any useable nodes. One 
full wave (an octave) would be end to end, with a node at the center. 
Then 1.5 waves (like a triangle) divides in thirds. The next harmonic, 2 
full waves, would have nodes at the 1/4s and 1/2. Etcetera. The length, 
from attachment point to ends, should be an integral number of 
half-waves, and I believe that the lower the harmonic of choice, the 
better the effect. Like the guitar technique Yes used in Roundabout...
