Lead-Sheet Symbols: Triads and 7th Chords

7th Chord Chart

Lead-sheet symbols are a tricky thing to remember. Even I, if I go too long without reminding myself about my sevenths, get them messed up.

On the chart above, you can see the 5 types of 7th chords and the 4 types of triads.

Let’s talk about the types of sevenths:
A major 7th has what would be the root of the chord and the 7th being a half-step apart (i.e., C — B)
A minor 7th has what would be the root and the 7th a whole step apart (two half steps. i.e., C — Bb)
A half-diminished 7th is also one whole step (two half steps)
fully diminished 7th is three half steps ( i.e., C — A)

These are just the 7ths. The triad is equally important in determining the type of the 7th chord.

Here is an abstracted version of the above chart:
Major Triad + Major 7th = Major 7th Chord (M7)
Major Triad + Minor 7th = Dominant 7th Chord (Mm7 / dom7)
Minor Triad + Minor 7th = Minor 7th Chord (m7)
Diminished Triad + Minor 7th = Half-Diminished 7th Chord (⦰7th)
Diminished Triad  Diminished 7th = Fully Diminished 7th Chord (o7) (Note that “o” is a radial sign)

“Why the white-notes?”
If you spell your sevenths without qualities, the “white-note” chords are their default position. C E G B is a M7,  F A C E is also an M7. G B D F is the only white-note dominant chord, etc etc. They are useful as a memory tool.

What does it look like in two different keys?

Notice how the minor 7th (m7) almost sounds major. This is because of the major chord that exists in the chord when the bass note is removed. C Eb G Bb, remove the C and you have a Eb major triad.

Delano, the Bus Driver.

Riding public transit in the Wenatchee Valley is usually pretty uneventful. The drivers are super nice, routes are usually on time (except in the winter), and the stations and busses are clean and safe.
I had a bus driver, let’s call him “Delano”, who wasn’t exactly friendly or very helpful.

Delano became our regular bus driver to Waterville. Waterville is a long-distance rural route from Wenatchee. You couldn’t hardly get a word out of Delano. He said “hello” or “good morning” when you said the same to him, and that was it. No smile either.

There was a girl who usually got on our bus when we reached the city. She got on every day, at the same spot and at the same time. She was a regular rider, along with the rest of us.

She forgot her bus pass one day. When Delano opened the bus door, she said: “I forgot my pass today.” Delano said: “No pass, no bus!”, shut the door, and began to drive off. Another passenger shouted: “Stop! I’ll pay for her to ride”, but Delano kept driving.

All of us were in shock.

We wrote our complaints to the city transit administrators. We knew Delano wasn’t in “the wrong”, but his actions were not very professional or humane; especially considering that he knew the girl did have a pass.

Quite a bit of time passed. I needed to take the bus to the hospital to visit a family member. The yearly route change had just occurred, and I knew that the hospital route had made a significant change.

I got on the bus, and guess who was driving?

“Shit!” was all that went through my mind. We took off at the scheduled time, and I knew we were getting closer. I tried my best to make sense of the new map, but it wasn’t happening. So, I took a deep breath and said: “Delano, could you let me know when we get to the bus stop nearest to the hospital?”

He replied: “Yes. Yes I can.”

And he did. He pulled right over at the stop for me. I didn’t even have to pull the stop string and make the bus produce that annoying “ding” sound.

I file this memory under: “Moments when I thought I was going to die, but things turned out alright.”

Delano, I suspect, may have gone to happy camp, making all the difference.

Pipe Organ Encounter Technical

This past week I was at a Pipe Organ Encounter: Technical (POET) event.

The regular Pipe Organ Encounter (POE) is an event for younger people who have little or no experience playing the organ to have the opportunity to receive lessons and see many different organs in a weeks time. The POE Technical is for organists to get a chance to see the inside of the instruments, learn how they are constructed, and get hand-on experience working with organs.

For the event, a group of 18 (including myself) stayed at Pacific Lutheran University in Tacoma, WA (except for a few commuters, who still reported to PLU at the beginning of the day) and spent a great deal of time seeing instruments all around the area.

The two organ builders that we visited were Paul Fritts of Paul Fritts and Company Organ Builders, and Martin Pasi of Pasi Organ Builders. These are, by all means, the two finest organ builders in the United States. They both build organs using historical methods. The goal is not to replicate historic organs, but to return to older and true methods of organ building that have been in existence for centuries. Both builders have been getting a lot of notice in Europe as well; and they certainly should, because every instrument they build is of the utmost and exceptional quality. Everything in their instruments is build to absolute perfection to a degree that I have never seen.

Both builders have a preference for wedge shaped bellows. Why? It makes the instrument BREATH! When a sudden demand for air is made, there is slight sag in the supply. This is just like the breath of a singer, or any wind instrument. The effect is magnificent. When not desired, additional “wind stabilizers” can be turned on to make the organ constantly speak absolutely steadily.

All but two of the organs we saw were tracker organs. A tracker organ uses completely mechanical means to operate the entire instrument. The only electrical parts in a tracker are the combination action (to assist the organist in making quick stop changes) and a blower. Most trackers lack a combination action. Many have the ability to manually supply wind (so one could turn off the blower and still have the organ playable… with the assistance of a person to supply the wind).
One of the non-tracker instrument was across the street from the PLU at Trinity Lutheran. The other was a theater organ in Gig Harbor.

I’ve seen, played, and worked on theater organs before. Most of my peers with me in the POET have never seen theater organs or played one. Some never knew what they sounded like. I was quite pleased to see that nearly everyone had an ear-to-ear grin on their faces when they heard the impressive playback of a concert by Jonas Nordwall, which included many of the percussions available in the instrument.

Overall, the event was fantastic. I hope to see more POE events for older students and adults that I can participate in, and I would suggest that others with a similar interest in playing and working on organs check this out.

Zylblog Changes

Zylblog is going to become a personal blog. Although I am still a computer technician, I really have very little interest in keeping up with the “latest and greatest” of technology. I have become considerably more focused on my personal studies in music theory and organ.

Computer-related posts will still be on the site and can be distinguished from other posts via. category selection. I simply have no intent of making this blog singularly focused on computer related content any longer.

Trouble with Windows XP SP1 and WPA networks?

If you are trying to get a Windows XP computer to connect to a wireless network that is running WPA and you’re having trouble, check to see if you have the most recent service pack installed.

When XP was released, WPA wasn’t something Windows did. Sp1 should allow for connection to WPA networks, and SP3 introduces more support and WPA2 support as well.
Your hardware must also be WPA compatible.

You may find that basic WPA support can be given by installing the updated issued by Microsoft for WPA support. This is available here:
https://www.microsoft.com/en-us/download/details.aspx?id=3914

Or, even better, install SP3. If you don’t want to use Windows Update to install SP3 for you, or if you don’t have Internet, you can download the entire package here:

Google Reader Retiring July 1st, 2013

Google has announced that it will be retiring Google Reader on July 1st.

I’m rather surprised. I happened to like this product, and I know quite a number of other people do as well!

Google announced on the Google Reader blog that the reasons for closure are due to a decline in product usage and a shifting in Google of focusing all their resources on fewer products.

I know I’m of the thought that the product was stable, why not just keep it there for those who would like to use it? We won’t complain about lack of updates over the years.

If you have an alternative program or webservice for Google Reader, do share in the comments.
