trumpetking sez: I know 10 of the scales, --- This may look a little outside the topic of memorization but a tool that's at your fingertips and useful in learning your way around the horn. Great news! You actually have 70 scales under your belt. Here's how it works: From C to C is the major scale right? Its also called the Ionian scale. D to D in the key of C is a Dorian scale E to E in the key of C is a Phrygian scale F to F in the key of C is a Lydian G to G in the key of C is a Mixolydian A to A in the key of C is a Aolean B to B in the key of C is a Locrian This works for all 10 of the scales you know. The purpose of telling you about this is so it can be practiced. You have to learn your way around the horn and get the sounds in your ears. You must develop physical and aural dexterity. Here's a little game you can play if you have a person you can play with. The other person can have any instrument. You copy them in your register " the trumpet register". Have the person play a small pattern. You play the pattern back perfectly. If you don't then you get one point. Take turns, first one to 10 loses.
