Column Label | Meaning |
Measurement |
Identification of the measurement in terms of detailed identification of the instrument as well as the person who did the measurement. Instrument detail includes maker, instrument name, collection and collection ID (if it is known). |
Reference |
That which the length in the following columns is measured in relation to; It can be the top of the joint, the bottom of the joint, the end of a tenon or even a tone hole. |
Bore Measurements |
There are two basic approaches to measuring elliptical bores. One would be to directly measure the maximum and minimum distances between the bore sides for a particular length into the bore. The second (and the one used exclusively for the measurements on this site) is to measure the distance a given rounded soft cross bar or rod will travel before lodging against the bore sides. |
Length values marked by x |
|
Length values marked by y |
|
Width | This is the distance between the sides of the bore when only one value is present. |
Ellipse Width Maximum at x |
When two distances between the sides of the bore are present, This will be the Maximum value in the direction that is consistently the maximum calue |
Maximum
Length |
When a particular distance between the sides of the bore are taken in an elliptical bore,
there will be two lengths that that distance falls. This is the longest of those distances. |
Minimum
Length |
When a particular distance between the sides of the bore are taken in an elliptical bore,
there will be two lengths that that distance falls. This is the shortest of those distances. |
Length
cross grain (x) |
When a particular distance between the sides of the bore are taken in an elliptical bore,
there will be two lengths that that distance falls. If the plane of the distance between the sides is recorded, this is the length when the diameter is taken in the plane of the centers of the tone hole axes. |
Length
cross grain (y) |
When a particular distance between the sides of the bore are taken in an elliptical bore,
there will be two lengths that that distance falls. If the plane of the distance between the sides is recorded, this is the length when the diameter is taken in the plane of the cross section of the tone holes. |
Diameter
cross grain at (x) |
In an elliptical bore, the major and minor axes of two ellipses are given.
This is the diameter of the bore at the lengths given above. It is also the major axis of the bore ellipse at the Length (x). |
Notes: |
Socket and Tenon reference:
The terms top and bottom are used to describe socket and tenon orientation in the notes field Top means "The end uppermost in the direction of the instrument air flow" Bottom means "The end furthest along in the direction of the instrtment air flow" |
