Notes: | 1 [value] |
Length- and Cross-wise tone hole angles are measured in reference to the axis of the bore It is a crude approxiamation based on a sketch of the tone hole angle (±10° or 15°) |
n/r | Indicates that the data for this field was not recorded | |
n/a | Indicates that the field does not apply in this instance. |
