Hi everyone,
Question - What part of a reed may affect a particular or range of notes?
For example, the blend at the side of the tip affect the stability of pitch of the High C on my Oboe (I need a sharp delineation).
Any other observations - hints - tips.
What have people observed - experienced.
You can also address reed opening/shape/staples/tie/ etc......................
(Can particular tubes affect particular notes or range of notes etc.)

Hi Mark --
Interesting topic. I've actually been thinking about writing up a little treatise on my experience with this, primarily for people like me who buy and adjust reeds, rather than make them.
Basic rules of thumb: taking cane off the heart and back lowers the pitch overall, and may make the reed less-resistant. Clipping the tip raises the pitch overall, and makes the reed more-resistant.
Taking off cane in the windows makes the low notes speak more easily (but can also lead to instability). Taking off cane at the top of the heart area can make the reed more vibrant (too much can make the tone thin).
Taking off cane along the sides of the tip (the "ears") makes the reed more responsive overall, and can "darken" the tone. Taking off cane along the top of the tip (don't scrape the center of the tip!) makes the high notes speak more easily.
Taking off cane just above the blend makes the tip vibrate more. You have to be really, really careful with this one, because it is very easy to take off too much. Just take a tiny, tiny bit.
These are the "fixes" that I use most of the time. If I had to do much more than these, I would find a different reedmaker!

Susan,
Thanks for your comments - on the overall reed adjustment. I find that taking a very light/small amount off the center tip heart blend also releases the lower notes to speak easier.
Yet, the question of interest to me - is - Is there a particular part of a reed that affects particular note(s)?
I find the corner tip blend has an impact on my Octave C. If the side tip blend is too blended (not sharply delineated) the note will be sharp.

Apart from the scraping considerations and those of staple size and shape silouhette, I have found the following:
Longer reeds (more than 72mm) tend to make the 2nd octave key notes flat with respect to the notes below low F. Shorter reeds (under 69mm) do the converse.
This is on a Loree standard bore from 1985. I'm sure that these observations are different on, for example, a Laubin.
