Here is an interesting project I did for myself. I was making an infographic of "how much it costs to be a bassoon student," and wondered what the average cost of a finished bassoon reed was. I ended up putting together this Excel sheet with as many reeds as I could find. (over +330) This is by no means a complete list, so please let me know if I should add any or correct anything!
The link should share that Excel sheet for viewing purposes only. The average price on this list is compiled from prices of "single finished reeds" for modern bassoon only. No blanks. Some are labeled as commercial brand as I suspect they are manufactured on a commercial scale.
Legere reeds are not included in the data average, but they are listed at the bottom of the sheet from various vendors. Bundled reed prices, sales, and discounts are not included. Shipping and additional taxes are not included. Reeds coming in 2020 are listed at the bottom. Converted dollar amounts are as of January 2020.
