How to use wind instruments plans
Here is the instruction manual to read and use all wind instruments plans I’ll share on this site:
On this page I share my work notes and personal plans, more or less well drawn, but still using the same system,
CAUTION – All lengths are millimeters!
The title contains:
– the flute type, side-blown flute, block flute, end-blown flute, notched flute,
– the flute tone, note and mode, in Anglo-Saxon notation. If nothing is specified, the note of the tone is also the fundamental note of the flute, the one you get when all the holes are close. For some flutes it is different (for example bansuri, peul flute), so I will note the tone then the fundamental note.
– the external-internal diameter of the pipe
The values under the holes are the distance from the end of the flute to the middle of the hole.
The values above the holes are the diameters of each hole.
The letters above the holes are the notes that are obtained by opening the corresponding hole.
The next steps are specific for each type of flute.
The value under the head is the total length of the instrument, measured between the middle of the mouthpiece and the end of the flute.
The value or values above the head corresponds to the diameter of the mouthpiece, and if it is not round, the length and width are indicated.
You must have noticed that there is a lack of information on the plan, the block size and the distance between it and the mouthpiece.
The length of the block does not matter, as long as the ensemble is sealed. Common sense wants it to be rather short, but free to you!
The distance d between the middle of the mouthpiece and the beginning of the block is always equal to the internal diameter of the flute.
Theorised by Theobald Boehm, the modern flute’s dad, which I always follow blindly (except from time to time,
but I will specify!).
The value under the head is the total length of the instrument, measured between the beginning of the bevel and the end of the flute.
The values above the head are the window’s dimensions.
Here too, some information is missing. The size of the block does not matter, the shape also can vary without affecting the sound,
an example of a simple form in the overtone flutes tutorial:
I do not document the shape and the size of the bevel on the plans, I will detail them on separate plans and in tutorial videos.
For oblique flutes, the value under the head is the total length of the instrument. No need for much about the mouthpiece, the preparation will be detailed on every type of flute.
For notched flutes, the value under the flute is also the total length of the instrument. No block either, I will just give the dimensions of the opening.
For the construction part, I prepare the article How to drill wind instruments, with all the secrets to perfectly drill (almost) every time, soon on this same site!
