The subject of positions is so confusing at the beginning. All it refers to is what key song you’re playing along with. So for a C harmonica:
1st position is playing in the key of C major
2nd position is playing in the key of G major, but with a bluesy kinda sound
3rd position is playing in the key of D minor
4th position is playing in the key of A minor
For those of you who are going through my course Beginner to Boss, I just wanna make sure that you’re aware that I teach a scale or two in each position (as well a several songs supporting songs) that provide a good sense of what the tonality of each position sounds like.
Module 3 Lesson 14 - Major scale and Module 3 Lesson 19 Major Pentatonic Scale both give you the sound of 1st position (Along with all the songs in lessons 16-30, and 46-48)
Module 3 Lesson 6 - the “Almost Blues Scale” and Module 4 Lesson 5 - The Actual Blues scale give you the sound of 2nd position (along with all the songs in Module 3 Lessons 2-12, and 49-51, as well as all of the songs in Modules 4,5,6 and 7)
Module 3 Lesson 31 - The D Minor Pentatonic Scale gives you the sound of 3rd position (along with the songs in Lessons 32-40)
Module 4 Lesson 43 - The A Minor Pentatonic Scale - gives you the sound of 4th position (along with the song Summertime in lessons 44 and 45)
If you’re ever feeling confused about the sound or geography of the harmonica as it relates to a particular positions, those could be helpful lessons to review. LMK if you have any other questions about positions!
