Scales in General
The tonal material of music arranged in order of raising pitches is a scale. There are a large number of scales because there are varies of tonal materials in different periods and in different countries (e.g. China). I shall show here the two main scales streams that are integrated in the European music: The Major scales and the Minor scales.

The Major scale tone intervals arrangement is: T-T-S-T-T-T-S (T = Tone, S = Semi-tone)
The Minor scale tone intervals arrangement is: T-S-T-T-T-S-T (natural minor scale)
The minor have two more variations beside the Minor Natural: Minor Harmonic: T-S-T-T-S-T+-S. and Minor Melodic: T-T-S-T-T-T-S.

Each scale can be transpose by starting from any tone from the twelve defined tones - but that change the key signature!

We shall practice Three Major scales and three Minor scales (each representing a group of scales). Play each one few times up and down.

Try to play all notes equal by their length
