The Scale Collection
Return to Ptools Page
These scales have been measured, recorded, and submitted by various Pscale users. They are, for the most part, "original factory scales". However, we do not always know that the strings we are measuring are, in fact, the original strings. While we can usually determine an original stringing there are situations where these issues can be incorrect. (strings that have been replaced using the original tuning pins in the block) Such practices will certainly affect a determination of an original scale and these issues should be kept in mind. In addition, some measurements (exposed cores) are often averaged and will affect the absolute outcome. Finally, these scales may be considered "original" with possible errors for whatever reasons.
I am including only "original as measured" scales at the present as I consider them the most interesting. It shows the current state of the piano scale and where improvements may be needed.
