3rd Position on a G harp

Musical Crossword Puzzles
I’m kind of a music theory nut. I just like playing scales, and I enjoy the puzzle of figuring out what scale and what position works best on a particular song. Practicing scales has made me more confident when I’m improvising or trying to figure out a melody by ear.

Third Position
Popular songs are great examples to think about in terms of their scale position. Lately I’ve been calling 3rd position the “Carlos Santana position,” because the Dorian minor scale, easily played in 3rd position, is used on “Soul Sacrifice,” “Oye Como Va,” and other Santana classics. But third position isn’t just for psychedelic Latin blues-rock! It works over lots of minor-key songs.

Last Dance with Mary Jane
For example, the Tom Petty song “Last Dance with Mary Jane” has harp breaks in the key of A-minor. Based on my own listening and experimenting, I think his specific harp part is played on a G harp in 3rd position. Before we get to the specific riff, though, take a second and practice the scale:

-4  5  -5  6  -6  -7   7  -8
 A  B   C  D   E   F#  G   A

This pattern will give you a third position minor scale on any harmonica, but on a G harp, it gives you these specific note names in the key of A minor.

What About the Riff?
For the Mary Jane riff, aim for 6 draw and follow this pattern:


Move slightly left (lower in pitch) while following this breath pattern, and you’ll figure out the part by ear. Remember to check with the original so you know how it’s supposed to sound. Put on the recording, listen, then sing it back to yourself.

Learn the Scale!
I highly recommend learning the 3rd position minor scale, starting on 4 draw, ending on 8 draw, and playing it up and down, forward and backward. Why? Because it gives you a roadmap that will contain Mary Jane’s Last Dance and other songs played in 3rd position, so the next time you come across a minor-key song played in 3rd position, you’ll pick it up faster.

More 3rd Position Songs

With your G harmonica, you can jam along and even figure out melodies to the following songs:

Soul Sacrifice – Santana

Oye Como Va – Santana

Stairway to Heaven – Led Zeppelin

Moondance – Van Morrison

If you get deeply into these songs, you’ll notice that Stairway and Moondance have a few spots where 3rd position doesn’t fit. For those spots, maybe switch to a C harp and play 4th position. Or you could stay on the G harp and avoid the 7 draw at those moments.

Rolling in the Deep

I got an email from a student recently – his band plays “Rolling in the Deep,” by Adele, in the key of C minor. What key harp to use?

Cross Harp on an F

2nd position on an F harmonica gives you C minor, as long as you’re precise about the 3 draw. EVERY time you hit it, make sure you land on it pre-bent a half step. If you play the 3 draw unbent, it will sound major, which is a lousy sound over a minor key song. Here’s the scale:

-2 -3′ 4 -4 -5 6

Also, unless you’re used to playing high harps, an F harp might be a little stiff feeling, especially when that precise bend on -3′ is required ALL the time. A low F might be nicer. Finally, even though cross harp is the most comfortable and familiar position for most players, it wouldn’t be my first choice. Personally, I’d go for 3rd or 5th positions.

5th Position on an Ab

An Ab harp will give you C minor in 5th position. Fifth position is great if you’re already comfortable with the MAJOR cross harp sound and can bend the 3 draw a whole step. Here’s the 5th position minor pentatonic scale:

2 -2 -3″ -3 -4 5

Compare to the 2nd position major pentatonic:

-2 -3″ -3 -4 5 6

Same notes, but starting and ending one note lower than normal.

3rd Position on a Bb

A B-flat harp gives you C minor, when you play in 3rd position. This is probably the easiest, once you’re used to it, especially the middle octave:

-4 -5 6 -6 7 -8

No bends required! The opening breath pattern (Draw Draw Blow Draw) is similar to cross harp, just starting on 4 draw instead of 2 draw. And you can bend on 6 draw for a flat-5 sound.

4th position on an Eb

Similar to straight harp (1st position), but with the root on -3″. Since your low root is a bent note, you have to learn to land there with confidence. Work on landing directly on your bent notes, rather than sliding every time.

-3″ 4 -4 5 6 -6

In the low octave, you won’t have a flat-5th unless you can overblow on hole 4, so when you also consider that Eb is also kind of a high-pitched harp, it’s not my first choice for bluesy sounds. For simply playing dark, minor sounds along the Do-Re-Mi seven-note scale, though, I’m all for it! Here’s the 4th position minor scale (7 notes):

-3″ -3 4 -4 5 -5 6

6th Position on a Db Harp

Just to be complete, let’s not forget that a D-flat harp will give you C minor if you play in 6th position. And the minor pentatonic scale is super easy using the middle octave in 6th position, no bends required. That is, as long as you don’t mind having a flat-5th ALL the time. Here it is…

-3 -4 5 -5 -6 -7

If you step carefully, it’s a really easy, dark, bluesy pathway. However, it’s easy to make unintentional international sounds by accidentally playing 4 or 7 blow and getting a flat 2 sound. That move gives you a flamenco, Arabic, klezmer-type sound, which is probably not stylistically appropriate, even if you have a fearless, boundary-crossing musical outlook.

Actually, I suppose 5th position holds a similar peril around the 5 draw. So whichever way you go, remember to practice the scale, learn your pathway, and be patient with yourself. Try not to jump out of your skin and become totally mortified when you hit weird notes. Everybody plays weird notes sometimes. Find your way back to the root and minor 3rd and hang there as needed.


If I were playing C minor with a band on “Rolling in the Deep,” I’d probably use an Ab harmonica in 5th position, or a Bb harp in 3rd position. Since I overblow, both those positions give me the option of a 7-note diatonic mode or a 5-note pentatonic scale. But even if you don’t overblow yet, 5th position gives you minor pentatonic using only standard technique and 3rd position works without any bends at all!


This advice assumes you’re playing fills and pure improv, not the song melody itself. The song melody uses the Aeolian minor, which is a minor with a flat 6th scale degree. It’s nice sometimes to follow the lead singer with the actual melody, so if you want that option, you gotta use 5th position in the low octave, or 4th position anywhere you like. 3rd position middle octave doesn’t have a flat-6th, unless you play an overblow on 6 blow, or transpose those phrases down an octave.
