| Column Label | Meaning | ||
| Instrument | These two columns contains the Maker's Name and the Instrument Name, | ||
| Measurer | The person who did the actual measurement. | ||
| Total Length |
Assembled length in millimeters; this number is often missing from the drawings. When it is missing, it is derived from the length of each joint minus the length of the tenons. Because it includes deductions of both tenons in order to arrive at the assmebled length, it will, of course, be off (too small) by as much as 4mm. Such derivations are indicated by an 1. |
||
| Acoustic Length |
The Acoustic Length is the length from the top of the assembled instrument to the center of hole 6. Because it includes a deduction of the head joint tenon in order to arrive at assembled length, it will be off (too small) by as much as 2mm. Such derivations are indicated by an 2. |
||
| Sounding Length |
The Sounding Length is the length from the top of the assembled instrument to the center of hole 8 (C). Because it includes a deduction of the head joint tenon in order to arrive at assembled length, it will be off (too small) by as much as 2mm. Such derivations are indicated by an 2. |
||
| Minimum Bore | The bore diameter ay it's narrowest point i.e. the cusp between the counterbore and the bore. | ||
| Bore Scaling |
The Bore Scale is the Acoustic Length divided by the Minimum Bore. Because The Acoustic Length has a probable error 0f up to -2mm, so also will the Bore Scaling have a probable error of up to -2mm. Such derivations are indicated by an 3. |
||
|
Aggregate Tone Hole (size) |
The sum of the sizes of tone holes 1, 2, 5 and 6. | ||
| Measurement ID |
A unique identifier for the measurement in the following form.
NNNN-XXXX-nn.m where NNNN is a four letter abreviation of the maker's name, XXXX is a four letter abbreviation of the Instrument name, nn is a unique sequence number for all instruments by this maker. m is a unique sequence number for all measurements of this instrument. |
