I love this song. I want to learn to play the harmonica to accent my guitar playing. I would like to be able to play this song more or less the same way it sounds here. What would be a good harmonica for this style/song? Key of A? I know nothing about harmonicas but I really love how it sounds in this song. Good example of harmonica accents at 3:45. Thanks in advance.

 

Key of A, but there was a B major chord in there, some chromatic movement, and a diminished D# chord.  Kind of a combination of E and A


Hope this helps


 

OK. .. Listened a couple of times..

Sounds like cross harp.. which would be using a harmonica keyed a fourth above the Key (tonic) chord.   So, if the song is in "A",  you would use a harp in "D".

Basically 3 Harp positions.. straight:  Song is in the key of "A", use an ":A"  Harp
Cross position.. Song is in "A", use a "D" harp..
Slant position.. Song in "A", use a "G" harp or the 7th of the root..( nit pickers may say.l that is a flatted 7th}, looking at from a pentatonic scale


All that being said..  A good harp player may "palm" an extra harp, so if there is a key change, modulation, or something of that nature... The player can transition to
the "palmed" harp to seamlessly continue the lick.

 Cross position, is probably the most used. You can quickly hear the bends and bluesy aspect..

My instant Blues replica harp noise is cross position through a Green Bullet into a fender champ

As Always, YYMV

Probable a Hohner chromatic in D.
