I really really REALLY love this song. It has always been one of my favorites. From what I understand the guitar solo is in E minor.
If I want to learn this on harp I can either (a) get an E minor harp, (2) play on my G harp but I need to learn to bend because E minor and G are related? Is this true?
Also I have looked online for Harp tabs for this section of the song and haven’t found anything, does anyone have anything?
Just stuff I think about when I can’t sleep…
It sounds to me like you need to learn more about playing diatonic harps. You have various options for the music piece: an A harp played in 2nd position, a C harp played in 5th position, a D harp in 3rd position, or a harp tuned for Em (which probably will be your easiest because it sounds like you are not able to bend yet). There are even more options, but why make this more complicated? With the A, D or C harps you definitely will need to know how to bend.
I have a tip for when you can’t sleep: practice bending. 
lol., I don’t think the others in the house that ARE sleeping would appreciate me practicing in the middle of the night.
I do need to learn more, I’m a beginner but playing that solo would be a holy grail moment.
LOFL 
– but, of course, Michael @michaelalexandermark you are right.
This forum has lots of good tips concerning bending and learning to bend. Search around – there is a veritable treasure of knowledge in this place.
Good luck, and don’t be afraid to ask – there are more than enough people who are more than ready to reply !! 
I’m assumming at some point in the distant future B2B will cover bending. I thnk I prob have a long way to go till doing that.
@michaelalexandermark Yes it does. With the excellent instruction Luke provides, as well as the great suggestions and experiences shared by the forum members, you will be bending in no time. When it happens you will likely be waking up the people sleeping just so they can hear you!!
@michaelalexandermark For Mother by Pink Floyd you’ll probably have the most fun playing along with a Natural Minor harmonica.
Lee Oskar calls it an Em harmonica.
Hohner (confusingly in my opinion) calls it and Am harmonica.
Hope that helps. LMK if you have any other questions. Rock on! 
Found this on YouTube any good to you.
It’s funny how people think in different ways and get the same understanding. It makes more sense to me to call it an A harp tuned to natural minor (A Nmin) because its an A harp (starts with an A on 1 blow with the appropriate notes flattened)
