How a keyboard diagram is interpreted

The typical keyboard diagram on this site contains 25 keys (15 white and 10 black) which makes it two octaves plus a key:
C major scale diagram
Covering two octaves makes it possible to use the same template over and over for different scales.

Keys that are included in the scale are colored blue. The second part of diagrams such as that below should not be understood that the part not colored doesn’t belong to the scale. All white keys on the keyboard are part of the C Major Scale.

Only one octave is used to present the notes in the scale, but that doesn’t mean that scales are limited to one octave. The reason for showing the scales on one octave is to simplify the reading of the diagrams (you can play the same notes on all octaves).

Where on the keyboard should the scales be played?

The diagrams don’t show all the keyboard since it would take up too much space (a full-size keyboard consists of 88 keys), neither is it necessary. A certain scale can be played on all octaves on the piano in the same pattern.

Why is eight and not seven notes included in most scales?

For example, C Major is presented with the notes C, D, E, F, G, A, B, C instead of C, D, E, F, G, A, B. Both variants would be alright, and the reason that the former is used on is partly because it is natural to include the second C before returning when exercising on a scale, and likewise when playing over several octaves, as in this sequence: C, D, E, F, G, A, B, C, D, E, F, G, A, B, C …

This doesn’t mean, however, that the C Major includes two C notes.

What does “Fingering (LH)” and “Fingering (RH)” stand for?

Fingerings are instructions of which fingers to use, see fingerings. “LH” and “RH” are abbreviations for left hand and right hand.

Why are double-sharps and double-flats sometimes used and sometimes not?

The use of double-sharps (e.g. F##) and double-flats (e.g. Bbb) are not always used in the written out notes directly under the diagrams since it could confuse beginners. They can instead sometimes be found further down the pages in the note overviews.

General questions

What is the use of scales?

The scales are useful shortcuts when trying to accomplish melodies, solos, licks and improvisation. Without knowledge of scales it is much harder to improvise and find melodies. By knowing scales, you have the knowledge of which notes that fundamentally fits together.

Scales are essential for many music styles. A guitarist playing flamenco, a saxophonist playing jazz or a pianist playing pop songs often use scales.

Which piano scales are most important to learn?

Since it is impossible to memorize all scales, you have to be selective. How many scales you learn depends on your ambitions as well. If you play piano only a few hours a week it would probably be hard to keep all that many scales in your memory. The first scales to learn are the Major scales, which are essential to understand keys and to get a better understanding how melodies are constructed.

The scales to learn should be decided upon your musical preferences. If you like blues, you ought to study the Pentatonic Blues scales.

How to memorize scales?

This is the hard part. As said earlier, the numbers of scales you can hold in memory depends to a high degree on how often you play. If you learn five categories of scales and take a break a couple of weeks there is a risk that you will have problems to recapitulate all of them. You need to learn scales and keep repeating them.

When learning scales in the same category, it will be easier if you observe that the intervals are the same. And if you want to learn many categories of scales, it will be easier if you compare them to each other and observe patterns. This is especially obvious then studying the modes, which all are variations of the major scales.
