Seven Natural Notes

A - B - C - D - E - F - G - A

​

Pattern repeats on the 8th note, called the octave.

​

I.2.Ba

Ambitus

range

​

The purpose of music notation is to represent some of the notes, or a range of notes, not every note possible.

​

Any voice or instrument has a set number of pitches it may sound; this is the range.

​

A bass cannot sing as high as a soprano and vice versa.

​

​

Range may also be used generally to refer to any set of notes; specifically indicating from the lowest pitch to the highest pitch of any group.

I.2.Bb

Lineæ Musicæ

music lines/staff

​

5 lines/4 spaces were not always standardized. Here we have a piece of early music that uses 4 lines.

​

Centuries ago, 5 lines/4 spaces had become the standard as it is legible and may represent the range of most instruments and voices.

​

The 5 lines and 4 spaces themselves have no meaning without a clef. Like any graph, the staff needs labels to carry specific meaning.

​

The clef's purpose is to label one of the 5 lines to represent an orientation note; since music has a set pattern, once one line is labeled, the values of the other lines and spaces are easily recognized.

I.2.Bc

Orientatio Clavis

clef orientation

​

Clefs show what range of music we are trying to represent.

​

Notice how each focuses on a different octave:

 

Bass: A=110 - A=220

 

Alto: A=220 to A=440

 

Soprano: A=440 to A=880

​

Each clef labels an orientation note on one of the 5 lines of the music staff.

​

The next episode goes into each clef in detail.
