Harp Key Chart
Harmonica Key Chart
Definitions:
Concert Key: This is the key that the band is playing in. You will also be playing in this key, but you may be using a different key of harp.
Straight Harp – Easy! the band plays in E then you use an E harp. No calculations needed. Straight harp is good for down home delta blues on the low side of the harp and shrill (but cool) Jimmy Reed style stuff at the high end. It tends to be simplistic and there are not a whole lot of good bend notes. Some of the usual bends used in cross harp are not available.
Cross Harp (2nd Position): This means to play in harp whose key is a fourth above the concert key. If you want to play cross and the band is playing in the key of A you count up on your fingers, 1-A, 2-B, 3-C, 4-D. So you use a D harp. Cross harp is the standard way of playing Chicago style blues. Lots of good notes and bends are easily found. Bend all the notes from 1 to 6 and they sound cool. There are very few bad notes in cross harp.
Slant Harp (3rd position): I have only rarely heard of third position being called slant harp, but it's a neat name, so I'll keep it. The slant harp concert key is one above the harp key. So if the band is playing in D step down 1 to a C harp. Slant harp has a minor sound to it and is good for minor blues. This is because the flatted third is available to the player without a bend. Always bend the 2 and 3 holes. All draw notes sound good. Don't blow until you are out of air.
How to use the chart. 1) decide if you are using 1st, 2nd or 3rd position. 2) go to the matching Concert Key column, 3) go town the column until you find the key that the band is playing in. 4) go to the left most column to find the corresponding harp key.

- What Harp Keys to Buy. This is what I carry around with me. Once in a blue moon the band wants to play something in another key, but I can usually talk them out of it.

your definition of cross harp in your explanation doesn’t match your chart
you said if concert pitch is A then you count 1-A , 2-B, 3-C , 4-D yet your chart says concert A use an E
im confused
The chart is right.
If the key of the song is A count up 4 to the D. Pick the harp that has a D stamped on it.
Go to the chart, find the key of D in the first column (it has the D stamped on it). Go to the right to find “A” the key of the song.
OK, now I’m confused. Please simplify. If someone says a piece is in the key of “A”, which column in your chart would that refer to?
Concert Key is A. That’s the key that the song is played in. Find “A” in the concert Key column and then go to the left to see what key is stamped on the harp. It says “D”. You use a “D” harp to play in the key of A.
Memorize these:
Song G use C harp,
Song A use D,
Song C use F,
Song E use A,
Song D use G,
Song F use B-flat,
Song B-flat use E-flat.
These will cover almost every situation. You need the B-flat and E-flat harps because these are used with keys used by brass instruments like trumpets and Saxophones.
My harp case has the harp key and the cross harp key painted on the slots. At 2 in the morning after a few beers it is easier to look at the key box rather than have to think.
Thanks for info I have played harp for 35 yrs and never knew what key to use or be in with a blues guitar riff
