This is page two of three pages, an article about the Hohner #267 Chromatica 48 Chord Harmonica, and it's evolution. Please see page one for historic background, and page three for Hohner-Suzuki comparisons. Page three will be posted tomorrow.
The Hohner 48 Chord Harmonica was invented circa 1930, to fill out the harmonies of the very popular harmonica bands and harmonica orchestras of the 1930s.
The mass-produced Hohner 48 Chord has wood combs, brass reed plates and reeds, rivets, nails hold the plates to the combs, and screws hold the nickel- or chrome-plated brass covers to the harmonicas.
The two harmonicas are held together with nickel or chrome-plated moveable brass hinges, one on the right side, and one on the left side of the harmonicas. The Hohner 48 Chord has 384 reeds, 192 blow and 192 draw. It measures 23 inches from left to right. The Hohner 48 chord harps are octave tuned (2 reeds an octave apart for each chord note), and are valved on every reed.
Many parts of the Hohner 48 have changed over the last 80 years: the logos (stamped, engraved or embossed) on the covers; the chord positions; the use of enharmonic spellings of the chords; and the language of the chords on the covers (German spellings, for the German market; or letter spellings for the rest of the world).
And, at least one model of the Hohner 48 (modern) uses inverted chords on the augmenteds, root chords on the other chord types. (Correction, 4-21-04: After re-reading the Hohner 48 Chord harmonica chord chart, it was discovered that the augmented chord are in root position, not inversions. Please accept my apology.)
Most of today's professional chord harp players ("chuggers") prefer the root position chords, that offer split chording (tongue-blocking) techniques to add additional chords not factory-installed. The 48 chord harps that have all inverted chords (Suzukis) don't have that possibility.
We will also include the Suzuki SCH 48 and SCH 24 harmonicas for comparison. The Suzuki chord harps have plastic combs, screws, brass reed plates and reeds (the reeds are welded to the reed plates). The Suzukis have inverted chords, and the SCH 24 has separate bass notes to the left of each chord.
48 CHORD HARMONICAS TABLATURE
Read the chord spellings from left to right, performer's side.
Chord Descriptions on the harmonica covers:
C = C major chord, root position, C-E-G-C; C inverted spelled E-G-C-E;
C7 = C dominant 7th chord, root position, C-E-G-Bb; inverted E-G-Bb-C.
Cm = C minor chord, root position, C-Eb-G-C; inverted Eb-G-C-Eb;
C+ = C augmented chord, root position, C-E-G#-C; inverted E-G#-C-E;
C dim. 7 or C-7 = C diminished 7th chord, root position, C-Eb-Gb-Bbb; inverted Eb-Gb-Bbb-C.
Some chord harps use enharmonic spellings to list the chords:
C# is the same sound as Db; G#= Ab, F# = Gb, etc.
HOHNER #267 Chromatica 48 Chord Harmonica, "Modern" Tablature (chord positions). This is the most common, most logical setup (tab) for the 48 chord harps. Let's call it the "Bill Morris" model. I've heard Bill play at a Windy City Harmonica Band rehearsal, and he is excellent.
HOHNER #267, CHROMATICA MODERN 48 CHORD HARMONICA TABLATURE (a guess: 1935-present)
Top Deck Blow | Gb | Db | Ab | Eb | Bb | F | C | G | D | A | E | B | Major chords
Draw | Db7 | Ab7 | Eb7 | Bb7 | F7 | C7 | G7 | D7 | A7 | E7 | B7 | F#7 | Dominant 7ths
Low Deck Blow |Gbm |Dbm |Abm |Ebm |Bbm |Fm |Cm |Gm |Dm |Am |Em |Bm | Minor chords
Draw |Db+ |Ab-7| Eb+ |Bb-7 |Bb+ |C-7 |G+ |D-7 |A+ |E-7 |E+ |F#-7| Aug.+/dim.-
On the Modern "Bill Morris" model, all chords are in root position. The name of the chord is it's lowest pitch. That allows the playing of extra, non-factory chords on the majors, minors, dominant 7ths and augmenteds.
Also note above that the major-dominant seventh vertical chord spelling is mostly parallel in both the top & low deck: Top deck Gb over Db7, low deck Gb minor over Db diminished 7th, etc. This is an easier pattern to remember than the earlier setup #1, seen below.
HOHNER #267, CHROMATICA 48 CHORD HARMONICA TABLATURE, SETUP #2 (a guess: 1933-1936?)
This model couldn't have lasted long, and is a rare find. Let's call this the "Al Fiore" model, as he reputedly used this
model to record the world famous 1947 hit, "Peg O' My Heart," with the Harmonicats. There were probably fewer than 50 of these made.
Top Deck Blow | Ab | Db | Gb | B | E | A | D | G | C | F | Bb | Eb | Major chords
Draw |Eb7 |Ab7 | Db7| Gb7 | B7 | E7 | A7 | D7 | G7 | C7 | F7 | Bb7 | Dominant 7ths
Low Deck Blow |Abm |Dbm |Gbm |Bm |Em | Am |Dm |Gm |Cm |Fm |Bbm |Ebm | Minor chords
Draw |Eb+ |Ab-7|Db+ |Gb-7 |E+ | E-7 |A+ |D-7 |G+ |C-7 |Eb+ |Bb-7 | Aug.+/dim.-
Notice that the "Al Fiore" model above has parallel vertical chords (top deck chords Ab blow, Eb7 draw, and low deck chords Abm blow and Eb+ draw. But on the "Bill Morris", the harp's major sharp chords are on the right half of the harp, and the the harp's major flat chords are on the left. On the "Al Fiore" model, half of the flat major chords are on the left end, and half of the flat major chords are on the right end, with the sharp chords in the center of the mouthpiece.
HOHNER #267, CHROMATICA 48 CHORD HARMONICA TABLATURE, SETUP #1 (a guess: 1930-1933?)
It's a guess that this is the original setup for the Hohner #267. I imagine that it would be difficult to remember the chord positions on this harp. It's extremely rare, probably fewer than 30 were produced. Let's call it the "Sam Sperling" model, after Sam Sperling, the chugger who used this setup with the Harmonica Harlequins, according to Stan Harper.
Top Deck Blow | Db | Gb | Cb | E | A | D | G | C | F | Bb | Eb | Ab | Major chords
Draw |Ab-7 |Db+ | Gb-7| E+ | E-7 |A+ | D-7 | G+ |C-7 | Bb+ | Bb-7 | Eb+ | Aug.+/Dim.-
Low Deck Blow |Ab7 |Db7 |Gb7 |Cb7 |E7 | A7 |D7 |G7 |C7 |F7 |Bb7 |Eb7 | Dominant 7ths
Draw |Dbm |Gbm |Cbm |Em |Am | Dm |Gm |Cm |Fm |Bbm |Ebm |Abm | Minor chords
Notice that the chord "flavors" (major, minor, dom.7th, aug. and dim.) are not in their "normal" positions (blow or draw). On this harp, the dominant 7th chords are blow, not draw, and they are located on the low deck. The aug. and dim. chords are draw, but are located on the top deck. The minor chords, blow chords on the other two Hohner 48 chords, are draw chords on the low deck.
Sam Sperling's great playing shows us that, despite the seemingly illogical tablature (chord placement) for these chords, Sam's playing was "sterling" with this harp.
