Remembering what has been said previously about how to find the notes on your fret board it should be a simple matter for you to locate all the notes with a little thought.
Firstly find middle C which is 5th string, 3rd fret.? It comes after B and before C#.? Play middle C with finger 1 and say the name to yourself as you listen to the sound.? Now locate the next C.? You will find it on the 2nd string, 1st fret.? It is 8 tones up from middle C.? Play this note.? It is still a C but higher in sound.? It is one octave higher.? Knowing where to find C anywhere on the fret board and knowing that it is always?
after B and before C# will be helpful as you progress..
Now that you know where C is try play notes CDE one after the other with the finger 1. ?Say each letter to yourself as you play the note.? Go slowly, sounding each note for at least a second.? You will have noticed that D is the 4th string played open and that E is the 4th string, second fret.??
Try locating the notes CDE elsewhere on your fret board, playing each note in turn.
When you are happy with your progress locate note F which is 4th string, 3rd fret.? It comes after E and before F#.? This sequence will always be the same wherever you find F on your fret board.
Exercise?
At this point test you skill by picking out the various notes at random:
B? G? D? A? E? C? F? D? A? F? E? B? G? D? A? E? G? B? G? C? E? B? D? G? C?
Play each note after working out the position yourself.? You should be able to play these notes without too much hesitation.? If you can't, stick with it until you are more confident.? A few minutes spent on this now will pay big dividends in the future.
Always think of your fret board as several small groups of alphabetic notes rather than one mass of unrelated notes.
You should now be convinced that there are only 7 basic notes in music named after the first 7 letters of the alphabet.
