> H-o-t-R-S is generally played in Am. Am-C-D-F--Am C-E etc... > Try a G harp played slant. This uses the 1d & 4d as tonic notes. >The scale you want is 4d 5b 5d 6b 6d 7d 7b 8d. > Try a Lee OsKar natural minor as well. The key would be Am unless I use an F harp or a low F harp sometimes for leads, or a G chromatic.
