Most of the people here know their 12 major scales and the chromatic scale, right? I hope so. Here's a little breakdown to show you that you know far more scales than you possibly thought! Most of you have probably heard of "modes". These are scales too.
If you know your twelve major scales, you actually know over 80 scales (12 major scales multiplied by 7). If you also know your chromatic scale, then add one more scale to the over 80 scales you know!
I'm using the C major scale to explain how it works but it works the same way for all twelve major scales. I'll throw in the E major scale too so you can see the pattern.
"From any note to it's octave in the key of (X) is one of the 7 Modes".
With trumpet in hand, play the following;
Play C to C in the key of C = the Ionian Mode
Play D to D in the key of C = the Dorian Mode
Play E to E in the key of C = the Phrygian Mode
Play F to F in the key of C = the Lydian Mode
Play G to G in the key of C = the Mixolydian Mode
Play A to A in the key of C = the Aeolian Mode
Play B to B in the key of C = the Locrian Mode
Here's the same thing but in the key of E major to show that this process works for all twelve major keys. Notice the process is the same
Play E to E in the Key of E major = the Ionian Mode
Play F# to F# in the key of E major = the Dorian Mode
Play G# to G# in the key of E major = the Phrygian Mode
Play A to A in the key of E major = the Lydian Mode
Play B to B in the key of E major = the Mixolydian Mode
Play C# to C# in the key of E major = the Aeolian Mode
Plat D# to D# in the key of E major = the Locrian Mode
I always like telling students who know their twelve scales, "You actually know a lot more than twelve scales". Oh, and if someone tells you modes are not scales, tell them to pound sand and to Google it.
Hope you find this helpful.
