Kniri 221  Alternate Tunings

Update:  27.10.2025

"CIRCULAR-KNIRI" tuning is a modification of standard circular (or spiral) harmonica tuning.

It is a special tuning that alters two notes from the basic circular tuning, making it suitable for improvisation and specific musical styles like jazz and blues. 

• Circular Tuning: The standard version, often referred to as "Basic Circular Tuning," has notes arranged in a circular pattern on the harmonica.
• "CIRCULAR-KNIRI" Tuning: This is a modified version that adjusts two specific notes from the basic circular tuning.
  For example, on a C harp, the 9 blow and 7 draw notes are lowered by a semitone compared to the basic circular tuning.
• Purpose: The modifications in "CIRCULAR-KNIRI" tuning are designed to offer different expressive possibilities and are particularly useful for playing jazz and blues.

 "CIRCULAR-KNIRI" tuning is a modification of the standard circular (or spiral) harmonica tuning, specifically designed for blues and jazz improvisation.
It was developed by the Swiss harmonica player Kniri Knaus. C.A. Seydel Söhne SEYDEL offers harmonicas with this and other special tunings. 

The "Circular-Kniri" tuning is a hybrid. It features the standard circular tuning in the lower half of the harmonica and the Kniri 221 tuning in the upper half.
This gives the player access to a blues scale across the instrument, without needing to use overblows or overdraws. 

The notes for a "Circular-Kniri" tuned harmonica in the key of C are as follows: 

• Blow notes: C / E / G / B / D / F / A / C / E♭ / G
• Draw notes: D / F / A / C / E / G / B♭ / D / F / A 

• Compared to the basic circular tuning, the "Circular-Kniri" version has two altered notes:
• Hole 9 blow is one half-step lower.
• Hole 7 draw is one half-step lower. 
•  

• Easy improvisation: The tuning is structured for easy access to bluesy and jazzy scales, making improvisation more intuitive.
• Full chord access: It provides a wide range of chords within a single key, depending on which holes are played simultaneously.
• Accessible bends: The layout allows for a variety of bends, including the key "blue notes," which are vital for blues improvisation.
• Broad range: It gives access to a three-octave range without relying on complex overblow techniques.

I was looking for an easier way to play the Blues with the common three chords (C, F and G7 in the key of C)
After playing around for some time I invented (2001) a continuous scale for diatonic instruments."Kniri 221"
The "diatonic-cyclic" tone arrangement makes it possible to play identical melodies in several major and minor keys.

On a 10 hole harmonica, this allows to play 5 different mixolydian major scales and 5 different natural minor (aeolian) scales,
which are related/similar to the circle of 4ths (and 5ths)
The tones have a regular spacing: 221221221221etc. 2=whole tone, 1=semitone
The nice thing about this is if you blow or draw any four notes right next to then it will always result in a flat7th-chord major,
diminished or minor, depending where you are.
This makes it very easy if you want to use the instrument to accompany someone and for improvisation.

The "diatonic-cyclic" tone arrangement "Kniri 221" makes it possible to play identical melodies
in several major and minor keys
(5 mixolydian and 5 natural minor (aeolian) scales) over an octave on the same instrument.
In a scale consisting of 20 tones, the 5 minor and 5 major scales over 1 octave each and 16 triads
in the circle of fifths/fourths are related to each other.
Always 3 tones next to each other result in a triad, alternating minor, major and diminished etc.
The chords fit together (tonic, subdominant, dominant = in C major: C, F and G7).
The tones have a regular spacing: 221221221221etc. 2=whole tone, 1=semitone
There are bluenotes: minor third and minor seventh (in C major Eb and Bb.)
This arrangement of notes is therefore ideal for playing in the blues scheme.

3. Mode

The third mode is based on the major third division of the octave
and divides the major third, the nucleus of the mode, into a whole tone
and two semitones; it can be transposed four times.
In the language used here by Olivier Messiaen
The shape starting from C with the whole tone step already applies
as the 1st transposition. In numerical form, this mode looks like this:
211211211 and has two reversals (112112112 and 121121121)
