**6.01 FLUTEKEY.EXE**Stand-alone program derives acoustic parameters of holes and keys for the Boehm flute and calculates effects of changes on intonation. See 1.35 and 6.02.

**6.02 INSTRUCT.TXT**Instructions for using 6.01, FLUTEKEY.EXE.

**6.03 FLUTRES2.BAS**Calculates the expected sounding frequencies for the Boehm flute in C, given the hole and key parameters. Prints an automatic plot for the entire scale, including trills, or will accept manual queries for a single note. See 1.35 and 6.04

**6.04 FLUTRESO.TXT** Instructions for using 6.03, FLUTRES2.BAS.

**6.05 EXPLRESO.TXT** Outlines the way the program 6.03, FLUTRES2.BAS operates.

**6.06 ALTRESO.BAS** Same as 6.03 except for Alto flute in G.

**6.07 BASSRESO.BAS**Same as 6.03 except for Alto flute in G.

**6.08 PICCRESO.BAS** Same as 6.03 except for Cylinder piccolo in C.

**6.09 HEADCONE.BAS** Calculates and plots the effective length of a C flute head joint as a function of frequency, using successive conical sections as an approximation to the taper. Routines for recurved heads and conical cork cavities included. Mouth height constant. Ref. 1.24 and 1.35.

**6.10 STRATHD2.BAS**Same as 6.09 except the mouth height varies with frequency to account for lip coverage changes.** **

**6.11 ALTOCONE.BAS** Same as 6.09 except for alto flute in G.

**6.12 BASSCONE.BAS** Same as 6.09 except for bass flute.

**6.13 CONEPICC.BAS** Calculates resonance frequencies for conical piccolo in C. Manual entry of fingering on line 90. Bore diameters entered in lines 510-630.

**6.14 PRESDIST.BAS** Calculates and plots the pressure, stored energy, and power flow along the tube of a Boehm flute in C for any fingering. Can choose assumed frequency.

**6.15 PRESCONN.BAS** Same as 6.14 except for cylindrical piccolo in C.

**6.16 MULTPHON.BAS** Plots the response of a Boehm flute to injected current at the mouth hole over the entire frequency range for any fingering. The resulting peaks show frequencies that may be sounded. Particularly useful for identifying multiphonics using unorthodox fingerings.

**6.17 PHASERES.BAS**Similar to 6.16 MULTPHON.BAS except that the phase is also plotted so that resonances that do not meet the feedback condition for sounding may be identified.

**6.18 MULTPICC.BAS** Same as 6.16 MULTPHON.BAS except for cylindrical piccolo.

**6.19 OBOEPRE2.BAS**Calculates and plots effective length of oboe air column, to examine the effects of variations in bore diameter. No finger holes.

**6.20 BASSOON.BAS** Calculates and plots the pressure distribution and loss distribution over the length of a conical tube having dimensions similar to a bassoon. No finger holes.

**6.21 CURWAVL.BAS** Time domain simulation of flute excited by jet. See paper 1.29 for description and 6.22 for operation.

**6.22 EXPLWAVE.TXT** Explains the operation of 6.21, CURWAVL.BAS, time domain simulation.
