There is often more than one way of writing a particular note. For example, the note F sharp can also be called G flat. These two notes have exactly the same sound and the same fingering.
Therefore, either spelling of the note may occur in the written music. This is called enharmonic spelling of the same note. The C Blues scale is often written using a Gb note instead of an F# note. The following example uses both versions of this note.
As with major scales, it is important to know the Blues scale in more than one key. Written as follows are the F and G Blues scales. Practice them until you can play them from memory and experiment with creating your own lines from them.
Here are some examples which make use of the F Blues Scale. Once you can play a melody, try playing it from memory with your eyes closed. This will help you learn the fingerings of the notes and also make you more aware of your tone.
