## How do I know if my violin is valuable?

I am not a violin expert. My goal is to find the top ten pieces in the history of music and to share that knowledge with the world. To do that I am going to use a very simple test: to see if the violin has a very high degree of value. If you can do even a relatively straightforward calculation for the value of a piece, then it will be included in this list. The goal of each musician is to find the top piece of music in the world. I won’t be giving the price of the piece myself. That has to be done by someone else. Why? Because even that can be a complicated problem and one I’m not very good at. What I can do is to calculate the amount of value I think the piece warrants. For example, the price-per-bar is a widely-used way of representing value-per-purchase which I will use as a benchmark. The price-per-purchase is how many times a piece is sold at a price equal or below the average retail price of that piece. If the piece has a very high price-per-purchase, that indicates either something special for this piano, or it is worth very little in the market. As for the number of times the piece has sold for a price less than or equal to average retail, that is not that important. What is important is that in the market value-per-purchase range the piece is worth something. Let’s look at the price-per-bar for a few pieces to see which ones are very expensive and have some history. I will use three modern violins (two modern and one late) in each example since they are a great number of years old. The price-per-bar of these three violins is approximately 4.8 million Bs. In our three examples these are the top ten:

Bridgetown (1295)

Schiff’s Violin Concerto No. 4 (1886)

Günther Buhl’s Concerto d’or (1896)

Dj. Bartok’s Concerto in F Major: “The Star-Spangled Banner” (1893)

Richard Strauss’s Violin Concerto in D Major (1893)

George Dantzig’s Concerto de la Barre Major (1895)

Rosa Luxemburg’s Violina in C minor (1896)

George Gershwin’s Concertino (18
