The key is the instrument, and in the case of a violin, the strings. The strings have a wide range, so to understand what a violin is, you’ll need to understand what strings are. In classical music there are four major strings: the violin’s major and minor octaves, the violin’s major and minor thirds, the violin’s major and minor thirds and the violin’s major seventh and minor seventh chords. The major and minor octaves are a standard stringing pattern within most concert halls, which is what you’ll hear playing in a concert. The major and minor thirds are a common string tension pattern, but not the whole set. You should know whether your major seventh and minor seventh are in a particular setting because you need to know whether a violin you see playing in concert is in the correct key.
Let’s start with an example. An example of the major and minor octaves is shown below. The violin has a major third, which is the highest string that you’d play in classical music. This is in an upper D tuning, the tuning of most concert halls. A violin will sometimes play in lower D tuning, so it’s also known as a minor seventh chord. Another example of a minor seventh is shown below. It’s the third string, in the A or G tuning of the instrument.
You have 4 strings: the first string, which is the first note played on a violin; the second string, which is the second note played on a violin; the third, which is the third note played on a violin; and the fourth, which is the fourth note played on a violin.
You might think a violin that has three or four minor thirds is missing out on these four strings and can’t play the same chords that the standard violin can. However, playing the same note on the third and fourth strings will give the notes of a chord that are not usually played. For instance, the 4th note of the scale you play on the 4th string (D) is played differently on a standard violin. On a standard violin there would be D, A, B, C, and D: The 7th root of G has not been played.
The key to understanding the difference between the two scales is to know which scale is used. A standard concert hall is in D tuning: B is low in key, as D is in G tuning. If you’re learning a musical instrument there are 4 major and 4 minor strings. Some instruments use only three
