The function of chords

This topic is going to be updated periodically as my understanding improves. As of December 2015 this is what I think I know about chords.

At first I understood that a melody  could have a harmony. This was based on my experience singing four part choral works and hymns in church. There was usually an accompaniment of some sort on the piano or organ or even in an orchestra. These accompaniments were not necessarily part of the melody but acted as a rhythmic source and a movement from one chorus or verse to another. That is about where I have been for many a year.

In undertaking my study of jazz over the last 10 years by reading jazz theory books and analysis I found that I just was not understanding the basics of music theory.

At this point I understand harmony to be those notes which are directly related to the melody. There may be different harmonies for the same melody. You have probably heard someone change the harmony notes for Happy Birthday or for Twinkle Twinkle, for example. The make it sound major or minor or like a tango, etc. That was a big step for me to understand that someone might compose a melody and then add some harmony to it later.

As a guitar player in my teens and twenties, chords were the rhythmic and musical accompaniment to my singing. In my 45 years of playing trumpet in shows and bands chords were part of the composers sonic creation.

Now, in learning jazz recently chords have a function (in classical music as well) that I am starting to understand. In a major scale using tertiary harmony there are four basic types of chords. Major, Minor, Dominant, and Half Diminished (also Diminished but less frequently used.)  There are many other places to learn how this is all related to the major and minor scales so I will not repeat that here. The function of a chord is to either move towards another chord or to resolve in preparation for another sequence.

The movement from one chord to the next is what I want to describe. Some time ago as I was starting to try to understand this mystery I corresponded with someone who gave me two chord progressions, one for major and one for minor. Since then I have found a large amount of resource material discussing these ideas. Basically however the progressions go like the following:

This image is from the site MusicTheory.net which is well worth a visit. With this understanding that there is some sense in music and that in many compositions both classical, popular, jazz, and more that there are patterns which are often repeated or slightly varied, my mind opened up to understand more along the path towards “Learn the Tune” which so mystified me.

In many standards and jazz classics the 2 5 1 progression of Minor – Dominant – Tonic is used frequently. What a nice name for the most stable chord – Tonic – sounds rather soothing!

The challenging tune – for me at least – All the Things You Are has the pattern

6 2 5 1 4 in Bb followed by 5 1 1 in D Major.

6 2 5 1 4 in F followed by 2 5 1 1 in A Major

2 5 1 1 7 3 6 4 in A Major although the 3 and the 4 are altered as 3D and 4D#5

6 2 5 1 4 in Bb Major followed by some altered chords b7 3 #2o and finally

2 5 1 1 in Bb major

The root motion rocks back and forth in a pattern in this song down 4 up 3.

I am at odds with my current teacher in thinking that the first 5 1 1 pattern could also be considered as altered chords of the first key of Bb. That would make them 7D 3M 3M

Sliding into the slot quickly

There is a trumpet player named Charlie Porter who posts videos on the internet teaching various aspects of trumpet playing. He posted a video in which he discussed what he called Straight Line playing. You should watch the video. Charlie Porter Video
The concept I want to discuss from this video is that your playing will slide into the nearest slot in the horn. Whether you want it to or not!
There is an article from Scientific American on brass instruments which my father had saved years ago. He was a French Horn player and a physicist. The article was by A. H. Benade and is titled the Physics of Brasses from the 1973 July issue.
These days you can get the article on line for a fee.
The critical part for this discussion is that the mouthpiece, tubes and bell of a trumpet work together to create standing waves in the instrument and the impedance of any tone either enhances or inhibits that tone. The tones with low impedance are the tones which are part of the typical musical scale. Mr. Benade also explains that the trumpet player begins a note and the wave travels through the horn until it is reflected back by the bell or by any other discontinuities in the tubing. The reflection returns to the lips and helps to feed back the horn response so that the lips can continue to buzz with the proper frequency.
Essentially, Charlie Porter and Mr. Benade are saying the same thing. You can play any sound/tone on the mouthpiece and the horn will attempt to push it up or down into the nearest slot. If you do not hear the tone in your head clearly and at the correct pitch you will miss the center of the slot. The horn will then crack or sound weak because the impedance for the tone you played will not be optimal.
One interesting note that Mr. Porter made in his video is that stopping and starting the air flow can be detrimental to your playing. I found that I have been doing that often. Dooo Weee with a slight break between the low note and the high note. He suggests that if you listen to excellent trumpeters you will hear that they do not do this. They will play DoooEeee and the transition as the note slides into the slot from above or below is very fast. He says to let the horn slot for you to handle difficult pieces and connect the air between the notes.
I’ve found that I have a number of these cracks and missed notes repeatedly in the same tune. I must not be hearing the tones in their proper pitch and/or playing them in the center of the slot. One of these for me is the E at the top of the staff.
 I’m going to work on pitching the mouthpiece properly for those intervals.
I’ve  already tried using a continuous air flow and tone and sliding it up or down quickly using the DoooEeee idea. This produced a much smoother and less cracked playing experience already.

The Minds Ear

Ingrid Jensen hosted a master class which was recorded on youtube.

Ingrid Jensen Master Class

In this class she covers a lot of interesting topics but the ones that leaped out for me are these two:

  1. Step away from the page and learn it one chord at a time.
  2. She would miss notes because her ears were not lining up in tune. She uses a drone tone to reference the tuning and help her ears hear the note.

To me these are so very important. Don’t depend on the page – use your ears.

I was welded to the page for years and years and I am only now starting to get free.

Use your ears – I thought of the trumpet as if it were a piano – push the right buttons and blow and the note will happen.

Why I thought of the second one the way I did is puzzling because my father always told me to hear the note in my head – my minds ear – and then play it. I never got it until recently and sadly my father passed away before I understood what he was telling me.

So if you hear a note that is slightly out of tune in your head and try to play it on your horn, your horn will respond. The trumpet will play any sound that you want to make. Some of them are good sounding and efficient and others are not. If you play halfway between C on the staff and C# on the staff, you can make that sound come out of your horn.

I am going to use the drone approach and will get back to this topic after some time practicing it.

Learn that tune

I’ve been seriously working on jazz for about 1 year at this point. One of the things that mystified and literally stopped me in my tracks over and over was the notion of what it means to learn the tune.

I’ve been a classical, theater, and pop trumpet player all my life – playing off of sheet music. One skill you need to have for that kind of playing is sight reading. You look at the sacred inscriptions on the paper and create sound in a faithful reproduction of what the composer intended. Usually you need to do this simultaneously with many others and you all have to more or less agree on what is supposed to happen!

You can memorize music so that you are essentially playing it from sheet music in your mind.

This is not what it learning the tune seems to mean at all. The tune is often written out in a fake book along with chords to play. Not much to go on for the classical trumpet player. However, this is where learning the tune really is. You need to be able to play the melody by ear. You can probably sing dozens of melodies easily. You may miss a note or two but you generally sing it correctly. You need to be able to do that on your trumpet too.

Still, that is not learning the tune.

You need to understand how the melody weaves its way through the rhythm and the chords. For every note in the melody there are alternate notes that could have been there which follow a different path through the harmonic space created by the chords. To learn this deeply get the Improvise for Real book and do the exercises.

You need to hear how each chord moves the tune along like the rises and falls, twists and turns of a road through a landscape. Once you start to understand the landscape you can take different paths which criss cross the original or go off on their own.

Learning the tune is understanding the harmonic landscape of it.

Now go home and learn the tune!

In the late nineties and early 2000’s I was single after 14 years of marriage and going out to clubs. I began to hang out at one restaurant that had live Jazz on Thursday nights and made friends with the band. I recorded their music for them for a few months. I finally got my gumption up and asked if I could play trumpet with them some night. They said yes. So, I madly practiced a number of tunes and settled on Secret Love which was in their book.

I was nervous. I rarely get nervous. But this was my chance to play some Jazz. Whatever that was to me at the time. I sure appreciated the music that these guys brought every week. I listened carefully to what they did and practiced mimicking it.

The night came for me to play. I was using sheet music which some bands do and some don’t. I played after the lead man sang the song. I launched into a solo. Having survived that we traded fours with the drummer. Then we played the tune and finished. I was flush with the feeling that I accomplished something.

Later, when the band was striking their equipment, the lead man said something like “Allright John, now go home and learn the tune. Don’t just noodle around.”

I was mystified.

I did not try doing that again for over ten years partially because of his comment and partially because I got married and have two children.

Noodle around. I thought at the time that is what a Jazz solo was! Just noodling around. I could never make much sense of many Jazz solos. Especially trumpet players who like to play loud fast and high. It sounded like noodling to me.

I determined to learn what was behind Jazz and started reading, doing Jazz theory workbooks, reading Jazz text books, and learning the nomenclature.

He don’t know the tune, Man!

When I lived in Houston Texas I got involved in something called the Jazz Tour. We traveled to night spots to hear live jazz. I knew it was music but I could not make sense of it. Some things really appealed to me like Thelonius Monk. Other things sounded like kids in the kitchen banging on pots and pans and playing kazoos. I understood Big Band music. It was written down!

We went to one club on the east side of Houston on the river, I think. There were two old cats in the front near the band stand. Each time the trumpet player would get up to do a solo, one or the other of them would start shaking their heads. After this happened a few times I sidled up behind them to listen in. The trumpet player put down his horn and the piano player started into his solo. The guy on the right leans over to the guy on the left and says “He don’t know the tune, man” and his buddy was nodding his head and saying “You right about dat.”

I was mystified.

What that trumpet player played sounded the same to me as what the sax man played and what the trombone man played. Those guys didn’t get the rough treatment though.

What on earth did they mean?

I’ve started to finally understand this and it has only taken me 33 years to get here.

Becoming Jazz

I am 58 this year and I am just learning to play jazz on my trumpet.

Yes I have played around with Jazz for many years and played lots of jazzy things in bands and in the orchestra pit for many a show but this year I set out to really learn to play jazz. Improvisational jazz.

I hope my experiences in this journey are interesting and useful to you now that you find yourself here with me.
