Fine tuning: equal temp.

Equal temperament

Besides the general note layout of the harmonica, which is the so called >Richter-tuning present on all of our instruments from the Blues series, harmonicas can be tuned to different temperaments. A modern harmonica must be a versatile instrument and has to fit into many musical styles. That is why we tune our serial models according to the so called "Compromised tuning". This tuning is very well suited for playing the harmonica in the first three (and most important) positions.

If you think of a harmonica in C these are G-major (2nd pos., Blues) or D-minor (3rd pos. Blues/Funk/Irish folk) or simply the 1st position (traditional music, Blues).

 

The pitch of the single notes of the scale is "fine-tuned" - that means that some notes of the scale are tuned with well defined deviations from the basic frequency (443 Hz). That is why chords still sound "OK" and all notes sound in the right pitch if played in the different keys given above:

Compromized tuning for playing in 2nd and 3rd position (SEYDEL's standard for all Blues instruments)

blow 0 -14 2 0 -14 2 0 -14 2 0
hole 1 2 3 4 5 6 7 8 9 10
draw 4 2 -12 4 -2 6 -12 4 -2 6
divergence in cents

 

If you divide an octave into 12 equal parts you will get the equal temperament:

12-tone equal temperament (12-TET)

blow 0 0 0 0 0 0 0 0 0 0
hole 1 2 3 4 5 6 7 8 9 10
draw 0 0 0 0 0 0 0 0 0 0
divergence in cents

 

This temperament (or fine-tuning) is suited especially for single note playing, because dissonances occur if one plays chords. These instruments are suited best for players who play the harmonica in many >different positions (e.g. in Jazz) and do use the >Overblow-technique.

If a player sticks to the 1st position to nearly 100 % (C-harmonica in C and G), then another temperament is the better choice: With the so called >Just intonation chords (C and G) and the notes major scale (C) do sound without any dissonances.


IMPORTANT: Please describe under "Order comments" in the shopping basket which of the harp(s) or reedplate(s) of the current order should be tuned to "Equal temperament" - surely there must be at least one harp/pair of reedplates in the basket ;-)!
