["Instructions for using the Flute Tuning Analyser"]
["Check all keys are sealing properly and temporarily fix any other sources of leakage."]
["Check that the stopper is set to its nominal position of 1 bore diameter back from the centre of the embouchure OR if the intended regime for moving the stopper is known, ensure that the stopper is adjusted appropriately for each extension."]
["Thoroughly warm up the flute by playing for several minutes. Mop out excess condensation."]
["Use a tuning meter capable of a wide range of reference pitches, eg Tatsuaki Koroda's Auto Tuner"]
["Use the traditional fingering patterns.  This usually means that all notes other than C, C#, D and d should employ the Eb key open.  If second octave e tends too sharp, close Eb for this note where it gives a better result.  Open the F key as well as Eb for F#, and the upper C key for C#."]
["Print out the Data page if desired to permit convenient data collection."]
["Press the slide fully in and note the pitch of a convenient note such as A4.  Enter the pitch at the head of the column, and 0 against the note chosen."]
["Record in the appropriate column of the spreadsheet the deviation from 0 of all the notes, constantly referring back to the reference note to ensure flute tuning is not changing.  Make embouchure adjustments if necessary to re-centre the reference note.  Be careful not to lip any of the notes being tested towards correct tuning."]
["Note that the areas of the spreadsheet where data are to be entered are not shaded and not protected."]
["When satisfied that the pitch has been accurately documented, measure and record the slide extension which gave that pitch.  Note that it is hard to achieve repeatability better than about 5 cents."]
["Pull the slide out 6mm (or as desired) and repeat the process.  Any other increment can be used, but must be entered on the table."]
["Examine the data for obvious anomalies, either directly on the Data page or on the Review page. You should expect that the measurements for each note should tend more positive as you go across the page, except for notes at the top of the tube, which should tend more negative.  You should also expect to see a more dramatic change in the notes at the low end of the tube.  If you find anomalies, recheck these measurements and record the new result."]
["Examine the various graphs on the Pitch page for indications of best pitch.  Indications are given by where a trace crosses or comes closest to the zero line."]
["The correlation between the Whole Flute, Foot, Low Octave and 2nd Octave curves provides an indication of how well the tuning of the various regions of the flute conform."]
["Once a pitch has been determined for the flute, set the flute to this pitch and determine the best fingering for the third octave.  Record this information and the deviations from ideal on the 3rd Oct page."]
