What is a musical Note, Pitch and Octave

What is a musical Note, Pitch and Octave? The musical note  represents a small bit of sound made by playing a particular instrument. In piano there are 12 notes, and are assigned alphabetical names from A to G and includes sharps and flats.

Musical notes are the building blocks of much written music. Musical notes can be identified by letters to make them easier to write and quicker to read.

In music theory, pitch classes represent the notes by the first seven letters of the Latin alphabet, (A, B,C,D,E,F,G). It can also be identified by the naming naming convention of Do-Re-Me-Fa-Sol-La-Ti

          Pitch simply refers how high or low a musical note is. You can easily understand it when you play the same note from the left to the right side of a piano keyboard.

It is basically a standard of highness or lowness of notes chosen in a musical performance.


     Octave  comes from latin word octavum , which means something in eighth position.

It is therefore an interval between one musical pitch and the next, normally of same note (at the eighth position).

For instance, If you choose to play a C note anywhere on the piano keyboard, an 8th note up scale from our chosen C note will be an octave higher.

There can be more than one octave of the same note depending with the piano keyboard layout as shown below

The most important music scales  are usually written using eight notes. The interval between the first and last notes is an octave.

For example, the C major scale is typically written C D E F G A B C, the initial and final Cs being an octave apart. Two notes separated by an octave have the same letter name and are of the same musical note.

The above fundamentals are vitals in the understanding of music. One must understand them carefully.
