So far you have learnt all of the modes derived from the C major scale. Each of these modes can be played in any key. Just as there are twelve major keys, there are also twelve possible starting notes for each of the modes.
Any note of the chromatic scale can be used as a starting note for any mode. This requires a knowledge of the formula for each mode. The scale degrees of each mode are listed below.
If you are serious about using modes in your playing (and any serious musician should be), it will be necessary to memorize the formula for each of these modes. Don’t try to memorize them all at once, take one mode at a time and learn the formula as it relates to the sound of the mode and experiment with it. All you need to work out of a mode in any key is the starting note and the formula. Here is the Dorian mode shown in four different keys. 69259 COMPLETE SAX PAGES 133-216 1/11/06 10:52 PM Page 155
A great way to become familiar with all of the mode formulas is to play them all starting from the same note. The following example demonstrates all seven modes starting and finishing on the note C. Once you know them in that key, try starting on each different note of the chromatic scale and playing all seven modes. This will take quite some time to master, but by the time you can do it you will be very confident in your knowledge of modes.
Once you know a mode in a new key, you should begin improvising with it in that key. This next example shows a line created from the E Lydian mode.
