 Henle Feilag in Munich continued to use metal plate engraving until the late 1990s because their editors were unimpressed with the quality of early computer engraving. At Henle headquarters we met with a man whose knowledge of metal plate engraving is rivaled by few people alive today. Hans Kühner gave us a fascinating demonstration of this ancient craft. One, two, three, four, five, six, seven. Now we're going to add something for the touchstone. Then comes the next touchstone. One, two, three, four, five. And then for the pralterl sign. These are the value of the notes. These strokes are then painted on the notes. Kicked and placed. Then later placed. This is a sketch. Violin keys. Note strokes. They have to be adjusted in the middle of the emergency line. Everything is done with an eye measure. Now I'm going to put the temperature value in. In this case it's on Dantino. Espresivo Asai. I take the corresponding letters from the satin box and put them on the previously drawn line and put letters for letters at the back. That has to be very exact. That's why the expression is stoned. And through this activity, we often did some work with the kaput in which the bowl was not really sharp or it was sanded too hard and then the signs were smeared or broken through. I don't make mistakes. Okay, you're ready to make mistakes. Okay. I take the corrective number and put the position on the back of the note or the note or the place I want to correct. This note is wrong. It's an E and it should be a G. And this position is then marked on the back of the plate. And then I take a small bubble stamp and drive the metal from the back to the front. Do you see that? So now the metal is turned from the back to the front with this thing. And the metal is relatively smooth and you can then smear it with a steel handle. And the bulb has to be repaired again. And the bow is also broken. So, that was only one note. That's the corrective. A decade ago, Hans Kühner put away his hammers and his punches and learned computer engraving. As he approaches his 70th year, Herr Kühner continues to work as a freelance engraver for Henle. For many years, Henle sent engraving work to the Stuart's printing company in Würzburg, which had a staff of about 30 music engravers. It was the second largest engraving supplier in Germany. The largest one was in Leipzig in former East Germany. The engraving plates from the Stuart's company are now stocked in the Henle archive in Munich and lovingly preserved. An old order book from Stuart's lists the works by composer and title and provides details of each engraving project. Henle has preserved Hans Kühner's workshop equipment and a small museum in the basement still displays these relics of the plate engraver's craft.
