American (international) encryption: What is it and what is it for?

American (international) encryption: What is it and what is it for?

When we look for a song to play it or see a tutorial on how to learn it, it is curious that instead of coming the names of the notes such as do, re, mi, etc. We find the letters C, D, E, etc. Have you ever wondered why?

This way of writing music is called American (Anglo-Saxon or international) cipher. In this cipher the letters of the alphabet from A to G are used. If we see it this way it is easier to remember the notes than if we see it our way starting with Do, which is represented by a C.

The letter A corresponds to the note of La. Why does American encryption begin on that note? The answer is very simple: (La) is the note that is used as a reference when tuning most instruments, and that is why it has been used as a base.

As you can see, the notes already have a name and to name the alterations the signs # and b to indicate that it is a sustained note or flat.

When we want to use this encryption to name chords it is possible to put only the letter when it is a major chord. Example: G (G major) and to know that it is another type of chord, Gm (G minor) G7 (Sol 7) ... etc. are used.

These are some types:

  • m - Minor Chord
  • M - Major Chord
  • dis (o °) - Decreased chord
  • aug - Increased chord
  • M7 - Major 7 Chord
  • 7 - Seventh Chord

There are more types of chords but that is the subject for another blog.
