This document is a spreadsheet designed to help lay out the tone holes on a woodwind instrument based on desired notes. It provides instructions for entering desired note frequencies and hole sizes. Calculations are then performed to determine optimal hole locations and diameters to produce the desired pitches.

4 de jul. de 2019 · The tone holes effectively act to shorten the length of the tube. Sound can radiate both through the open tone holes and the end of the tube. To some kind of first approximation, you can just use the distance to the first open tone hole as the effective length of the tube and calculate a frequency by taking that to be 1/2 or 1/4 of a wavelength.
Flute Spreadsheets This spreadsheet is intended to partially automate the design of tonehole layouts for woodwinds, by calculating the effective length corrections for bores with tone holes. As it is, it is set up for a cylindrical PVC flute that plays an F major scale, using 6 or 7 holes.
The spreadsheet P:\Physics\phoekje\phy101\supplies\flute.xls has been set up to automatically calculate the length corrections for woodwind tone holes. Open Excel, choose File|Open and find this file, and then choose File|SaveAs to save it in an appropriate folder on your H: drive.
Find a flute you like and use one of the Physical Methods to replicate it. Use the NAFlutomat tool, an on-line calculator for placing holes on pentatonic minor mode 1/4 flutes. Follow one of the Plans for Flute Making. Use the Flute Sheet Excel spreadsheet that is available for download.
