Here are a few slide chromatic harmonica note charts for comparison, from Pat Missin's website. They may help you to determine the best note placement for your playing styles, or might help visually to explain the major (solo system), Richter (chord system), augmented and diminished note placements.
www.patmissin.comFor more information, or custom-made augmenteds and diminished harps, go to:
www.harponline.dewww.seydel1847.comThese charts are for a key of C solo system, C Richter, C augmented system or C diminished system harp, using a 12-hole model. There are more augmented and diminished variations at Pat Missin's website, but, for comparison, each of the following setups starts on hole 1 blow, slide out as a C note.
On the charts, large letters are blow notes, small letters are draw notes. The sign (|) represents hole divisions.
Some Hohner models have a D note replacing the B# note in hole 12, on the solo system harps.
SOLO SYSTEM (Major scale) key of C, horizontal reed placement, as Seydel Chromatic Deluxe.
Three complete chromatic octaves in 12 holes. Redundant C notes between octaves:
Hole: 1 2 3 4 5 6 7 8 9 10 11 12
Slide out:||C d |E f |G a |b C |C d |E f |G a |b C |C d |E f |G a |b C ||
Slide in: ||C# d#|E# f#|G# a#|b# C#|C# d#|E# f#|G# a#|b# C#|C# d#|E# f#|G# a#|b# C#||
RICHTER SYSTEM (Major scale w/chords), Key of C, horizontal, as Seydel Chromatic Deluxe Richter.
One complete chromatic octave only, holes 4-7. No redundant C notes between octaves:
Hole: 1 2 3 4 5 6 7 8 9 10 11 12
Slide out:||C d |E g |G b |C d |E f |G a |b C |d E |f G |a C |d E |f G ||
Slide in: ||C# d#|E# g#|G# b#|C# d#|E# f#|G# a#|b# C#|d# E# |f# G#|a# C#|d# E#|f# G#||
AUGMENTED SCALE, #12.4a, at Pat Missin's website (Pat lists a 10-hole, this is extended to 12). Four complete chromatic octaves in 12 holes. Augmented harmonicas are special order harps. Dr. Yeardon holds the United Kingdom patent for this note placement system. There are no redundant C notes between octaves. It's named the "C Augmented Slippy" at Harponline (Theirs is an 8-hole example):
Hole: 1 2 3 4 5 6 7 8 9 10 11 12
Slide out:||C c# |E f |G# a |C c# |E f |G# a |C c# |E f |G# a |C c# |E f |G# a ||
Slide in: ||D d# |F# g |A# b |D d# |F# g |A# b |D d# |F# G#|a# b |D d# |F# g |A# b ||
C DIMINISHED SEVENTH. I couldn't find the C diminished 7th scale at Pat Missin's website, but, since it's the same scale (in inversions)as the D# diminished 7th, F# diminished 7th and A diminished 7th scales (all of these contain the C note ), the C dimi 7 scale is created.
Here's the C dimi 7, starting with a C note at blow hole 1, slide out. With this note placement, duplicate d# (draw) and D# (blow), f# and F#, a and A, and c and C occur throughout the 3-octave range of the harp.
The diminished seventh slide harp is fully chromatic. It looks good for melodic playing, but the chords are not the normal major, minor or seventh chords used in most music. I have't seen this note setup anywhere else, but if you like it, you might have it custom-made at Seydel or Harponline, or by your favorite slide chromatic customizer.
Hole: 1 2 3 4 5 6 7 8 9 10 11 12
Slide out:||C d |D# f |F# g# |A b |C d |D# f |F# g#|A b|C d |D# f |F# g# |A b ||
Slide in: ||C# d# |E f#|G a |A# c |C# d#|E f# |G a |A# c|C# d#|E f# |G a |A# c ||
