Tip for reharmonizing

Claim:

Within each of these three groups the chords are interchangeable:

Group 1: C7b9, Eb7b9, F#7b9, A7b9, Edim, Gdim, Bbdim, C#dim

Group 2: Db7b9, E7b9, G7b9, Bb7b9, Fdim, G#dim, Bdim, Ddim

Group 3: D7b9, F7b9, Ab7b9, B7b9, F#dim, Adim, Cdim, Ebdim

Proof:

(Without restrictions only for group 1)

C7b9: C E G Bb Db

Eb7b9: Eb G Bb Db E

F#7b9: F# A# C# E G

A7b9: A C# E G A#

Edim: E G Bb Db

Gdim: G Bb Db E

Bbdim: Bb Db E G

C#dim: C# E G A#

The diminished chords are all made up of the same notes. The dominant seventh chords with the flat nine have common tones with the diminished chords, only the root differs. When replaced, the different root can be viewed as an altered tone that increases tension. With a dominant seventh chord, this tension is desired and is usually subsequently resolved by a major or minor chord.

Shuteen Erdenebaatar

I want to recommend the album “Rising Sun” by the Shuteen Erdenebaatar Quartet. She comes from Mongolia and studied jazz piano and jazz composition in Munich/Germany. I think she is as talented as Joey Alexander. The album contains many hymns to life. My favorite track is the melancholic piano solo piece “Summer Haze.”

Sifting Gold

“You have to sift the gold!” Jazz coach Brent Vaartstra says to his students. You have to decide for yourself which advice or course is best for you at the moment. What you want to put the most effort into improving now. Many things may still be too difficult, need more time or can only be achieved in small steps.

Since 2007 I have been making more music again, on saxophone, piano and clarinet. Sometimes I have more time, sometimes other things are more important. That’s life. I’m glad I’m doing ear training. I’m not very far along yet, but at least I can recognize intervals. In Darmstadt I played in workshop bands, in Paderborn I currently have time for saxophone lessons.

The question is whether well-placed tones can solve problems. Probably not directly, but you feel more relaxed and optimistic, which is certainly helpful. Art makes our world more beautiful.

Jazz Theory

I would like to recommend two courses to you because I believe that as a musician your life will be easier if you have studied the basics of music theory. Do you want to know what tones make up the chords and scales? What chord progressions are common in jazz?

There is the “Zero to Improv” course on learnjazzstandards(dot)com, which is a great way to get started. The “Jazz Theory Unlocked” course on jazzadvice(dot)com helped me understand the elements of a jazz composition. The chapter on the use of diminished chords was also enlightening.

These two courses helped me further.

The Music of Jürgen Wuchner

Recently, a German book on Jürgen Wuchner and his compositions was published by Wolke Verlag, edited by Monika Schießer-Wuchner:

Serendipity. Jürgen Wuchners Kompositionen

Click on the link and scroll down the page. You see “Bb- und Eb-Stimmen zum freien Download”. If you click on that field, you get the sheet music for Bb and Eb instruments.

I hesitated to make this free download public. I recommend buying the book so the publisher and the authors get their fair share. Even if you do not speak German, there is the sheet music for C instruments. I am writing this article to help proliferate Jürgen Wuchner’s music.

 

The Beginner’s Blues Accelerator

It is just a proposal inspired by the Jazz Blues Accelerator on LJS (learnjazzstandards(dot)com). This small accelerator has three steps:

1. Play the roots of the chords of a blues in all 12 keys.

2. Know the blues scale in 12 keys.

3. Improvise over the blues scale in 12 keys.

Some explanations:

1. Take a blues in C and play half notes:

C C F F C C C C

F F F# F# C C A A

D D G G C C G G

For bar 8 to bar 11 it is good to know the circle of 4ths, aka “the cycle.”

Then do the same for a blues in F, and so on.

2. The blues scale is the minor pentatonic with the tritone. For example:

C Eb F F# G Bb

Find it in the other 11 keys.

3. As a piano player, play the roots of the chords with the left hand, with the right hand improvise over the blues scale.

As a horn player, create a play-along, e. g. with Band in a Box or iReal Pro.

The chords are

C7 F7 C7 C7

F7 F#dim C7 A7

Dm7 G7 C7 G7

(one chord per bar)

 

Sunny Side

Joyful songs are important, particularly in difficult times. I wrote a contrafact over the harmonies of “On the sunny side of the street” and memorized it. I recorded it with the soprano saxophone and Band in a Box.

The lead sheets:

Sunny_Side_Contrafact-C    Sunny_Side_Contrafact-Bb    Sunny_Side_Contrafact-Eb

 

Farewell to Darmstadt

view from balcony

Another part of my life came to an end in October. Writing about it puts the question in which attitude I do it. I want to write thankfully. In 2009, I came to Darmstadt. First I worked at the Technical University, then at the accelerator GSI. I wrote a monography. For 10 years I took part in the workshop band of Jürgen Wuchner who died in 2020. Eight times I participated in the Jazz Conceptions, a one week summer workshop. I enjoyed the vibrant music scene, especially the concerts at Jazz Institute and at Knabenschule. The Frankfurt Radio Big Band played at Centralstation. Darmstadt also has a Staatstheater (public theatre) with opera. Each summer the Jürgen Wuchner Workshop Band gave a promenade concert in Orangerie Garden if it did not rain. I feel sad that I had to leave friends. Certainly will I return as a visitor.

In My Dreams

Are you curious what I am dreaming of? I am going to tell you, musically. It is an admittedly short composition, but for three tenor saxophones. On account of the pandemic it is hard to get three saxophonists together, so I recorded myself thrice.

Here you find the written composition:
