First Scale

Today we will look at the A major scale.
What is a scale? In a scale you play all the notes of a key signature in ascending and descending order.
Where are scales used? Scales are used in music exams. Anyone who has sat a piano exam will remember the hand motions involved in playing a scale. They are also handy when playing styles such as jazz which often rely on improvisation.
Why should I play scales on the guitar? Scales are useful to hear the notes that sound "right" together. When playing a melody or composing your own pieces, it will help you figure out quickly what notes are out of place and why.
How should I play scales? Each note should ring out for the same length of time. Scales should be played fluidly so there is no long gap when moving from one string to the next. When scales are played well, they should sound steady in terms of noise and speed.
What notes am I actually playing? You are playing A B C# D E F# G# A while ascending. Once you hit the high A, you descend backwards through G# F# E D C# B A.
