How to use a Diminished chord in a 1-6 progression

When going from 1 down to a 6, you can play substitute the 6 part with a 1diminished chord over flat 5.

E.g. In the key of Cmajor if you are playing a 1-6-5 melody from a C to A and then G, on the right hand you play

C C+D#+F#+A C+E+G

On the left hand you play 1 flat5 5. In the key of C that will be from a C to F# to G.

A Nice Run to Play Before the 1 Starting Chord

Hi folks,

In this post I will talk about a nice run to play before the starting 1 chord of slow gospel chords.

On the left hand, you go

3 4 5 6 7 1

e.g. in the key of C major, you will go


On the right hand you will harmonize the following melody:

3 4 3 2♯ 2 1

by using the following chords:

1 4 3minor 2♯-minor 2minor 1.

In the key of Cmajor these chords are:

G+C+E A+C+F G+B+E F♯+A♯+D♯ F+A+D E+G+C

That is:

First chord you harmonize the E using a Cmajor chord
Second you harmonize the F using a Fmajor chord
Third you harmonize the E with a Eminor
Then you go down a half step with the same chord shape to harmonize the D♯ with a D♯ chord
You then harmonize the D with a Dminor
Then you harmonize the C with a Cmajor chord.

To make it more melodious, on the right hand you can insert a 1sus4 chord before the last 1chord. That is, insert a Csus4 chord before the last Cmajor chord. So instead of going from F+A+D to E+G+C on the right hand, you can play it like this:

F+A+D  F+G+C  E+G+C

Furthermore, you can make the left hand run a little more melodious by quickly adding a 2 before the 5 since 2 normally has a strong pull to 5. So the left hand run becomes

3 4 2 5 6 7 1

To summarize, on the left hand you play the following notes

3 4 2 5 6 7 1

while on the right hand you play the following chords:

1 4 3minor 2♯minor 2minor 1sus4 1.

In the key of C, on the left hand you play:


while on the right hand you play:

G+C+E  A+C+F  G+B+E  F♯+A♯+D♯  F+A+D  F+G+C  E+G+C

Below is a recording.


The 9 (add 6) Chord

Hi folks,

I will like to talk about the 9 (add 6) chord. This chord is a nice one to use in worship songs.

You can use this for the 2 chord or the 1 chord.

E.g When playing a 6-2 progression, you can play a minor 9 for the 6 chord and a 9 (add 6) for the 2 chord. Similarly, when playing a 5-1 progression that does not end a song, you can play a 5 minor 9 chord, then a 1 9 (add 6) chord.

Here’s an example of such a chord.

D 9 (add 6)

To play it, you play D on the left hand. Then play F B B and E on the right hand.

An easy way to think about it is to play the root note of the chord on the left hand, then play a quartal 3 chord with an added ♭5 on the right hand.

For example, F is the 3 chord on the D major scale. F B and E is the F quartal chord. And B is ♭5 on the F scale.

Using this trick, it is easy to play 9 (add 6) for any key. That’s all for now. Enjoy.

How to fix error Unsupported major.minor version 52.0 when syncing Gradle Script Android Studio

Hi folks,

Recently when trying to run an Android project in Android studio, I noticed the following error on opening it:

Unsupported major.minor version 52.0

After doing some Google search I found that the problem was due to the code requiring Java 8 while my IDE used Java 7. So, to fix it one has to

– Go to File > Other Settings > Default Project Structure…

– If your JDK location is set to a Java 1.7 location, change it to the corresponding Java 1.8 location. In my case the required path was


– Click OK

That’s it. Now the error should go away.

Some Cool MS Excel Features: Filtering and Easy Average Calculation


Today I will go over two cool features I like in Ms Excel. Filtering and easy Average calculation.

Filtering is very useful if you end to extract subsets of data. To access filters in Excel, first create a table from a range of data.

To do this, highlight the entire table, then click Insert > Table. Then click OK to confirm the cell range to use for creating the table.

With a table you can apply filters easily.

To calculate average easily for a column of values simply highlight the column and the average, count and sum appears on the bottom status bar.

That’s all for now. Till next time.

A Cool Way to Debug JavaScript Applications using JetBrains IDEs

Hi folks,

It’s been a while, but in this article I will briefly discuss a very nice way to debug JavaScript applications when using JetBrains IDEs. For those who are unfamiliar, JetBrains is a manufacturer of very powerful and elegant IDEs for developing applications in a variety of languages. The first one I came across and loved is PhpStorm, the best IDE I’ve come across for PHP application development. I’ve also gone on to use others including PyCharm, IntelliJ IDEA and, most recently, WebStorm. Okay back to business.

So, to the issue at hand. JetBrains has an excellent Chrome extension called JetBrains IDE Support Chrome Extension which allows you debug JavaScript code in Chrome using WebStorm, PhpStorm, IntelliJ IDEA Ultimate, PyCharm Professional and RubyMine. It’s available on the Chrome Web Store for download. You can set breakpoints, step through code, view variables and do various other activities once this plugin is installed and activated.

I have used it recently and it works pretty well. This reduces the need for console logs. It’s also more convenient than having the write ‘debugger’ statements in code. So, if you write a lot of JavaScript applications and use JetBrains IDEs, then try out JetBrains IDE support today. Till next time.

An Interesting 2-5 Progression

When playing a 2-5 progression, here’s a way to add a few interesting chords in between.

The principle is that you walk up from the 2 chord to the 5 chord.

i.e. 2 3 4 ♭5 5.

Alternatively, to make it easier, you can take out the 4 and walk up as follows:

2 3 ♭5 5

An example of this is:

2minor7 1maj/3 4maj7 ♭5(with a quartal chord of its flattened 7th note) 513

The fourth chord there deserves more explanation.

Let’s assume we are in the key of D, what does a ♭5 (with a quartal chord of its flattened 7th note) mean?

Well, first ♭5 tone of D♭major will be G.

The 7th note of G major is F

Then we play a quartal chord of F (F B E) on the right hand over G on the left hand.

In the key of D♭ the walk-up will be as follows

Chord LH RH
E♭minor7 E B D G
D♭major / F F A D F
G♭major7 G F B D
G (with a quartal chord of its flattened 7th note) G F B E
A♭13 A G B D F

Below is a recording of the first variant:

And of the second variant.

I use the second variant in Thank You Lord posted earlier. See if you can spot it!


How to Document Django Applications with Sphinx

In this post I go over how to automatically document Django applications. By this I refer to a way to run a tool that automatically reads your projects and docstrings and generates beautiful documentation. Sphinx is an excellent tool for the job. Sphinx makes it easy to create beautiful intelligent documentation for projects. It uses reStructuredText as its markup language. Here’s how to go about it.

First install Sphinx using the command:

pip install sphinx

Initialise Sphinx


You will be asked several questions which will be used to generate a configuration file, a few folders and possibly a Makefile. You will want to make sure you enable autodoc to allow generating documentation from docstrings as well as the generation of Makefile so that you can run the make command in the future to update documentation. Below is an example of the what the screen looks like for these

Welcome to the Sphinx 1.6.1 quickstart utility.

Please enter values for the following settings (just press Enter to
accept a default value, if one is given in brackets).

Enter the root path for documentation.
> Root path for the documentation [.]: ./docs

You have two options for placing the build directory for Sphinx output.
Either, you use a directory "_build" within the root path, or you separate
"source" and "build" directories within the root path.
> Separate source and build directories (y/n) [n]: n

Inside the root directory, two more directories will be created; "_templates"
for custom HTML templates and "_static" for custom stylesheets and other static
files. You can enter another prefix (such as ".") to replace the underscore.
> Name prefix for templates and static dir [_]: 

The project name will occur in several places in the built documentation.
> Project name: Your Project Name
> Author name(s): Some Author Name

Sphinx has the notion of a "version" and a "release" for the
software. Each version can have multiple releases. For example, for
Python the version is something like 2.5 or 3.0, while the release is
something like 2.5.1 or 3.0a1.  If you don't need this dual structure,
just set both to the same value.
> Project version []: 0.1
> Project release [0.1]: 

If the documents are to be written in a language other than English,
you can select a language here by its language code. Sphinx will then
translate text that it generates into that language.

For a list of supported codes, see
> Project language [en]: 

The file name suffix for source files. Commonly, this is either ".txt"
or ".rst".  Only files with this suffix are considered documents.
> Source file suffix [.rst]: 

One document is special in that it is considered the top node of the
"contents tree", that is, it is the root of the hierarchical structure
of the documents. Normally, this is "index", but if your "index"
document is a custom template, you can also set this to another filename.
> Name of your master document (without suffix) [index]: 

Sphinx can also add configuration for epub output:
> Do you want to use the epub builder (y/n) [n]: 

Please indicate if you want to use one of the following Sphinx extensions:
> autodoc: automatically insert docstrings from modules (y/n) [n]: y
> doctest: automatically test code snippets in doctest blocks (y/n) [n]: y
> intersphinx: link between Sphinx documentation of different projects (y/n) [n]: y
> todo: write "todo" entries that can be shown or hidden on build (y/n) [n]: y
> coverage: checks for documentation coverage (y/n) [n]: y
> imgmath: include math, rendered as PNG or SVG images (y/n) [n]: y
> mathjax: include math, rendered in the browser by MathJax (y/n) [n]: 
> ifconfig: conditional inclusion of content based on config values (y/n) [n]: 
> viewcode: include links to the source code of documented Python objects (y/n) [n]: 
> githubpages: create .nojekyll file to publish the document on GitHub pages (y/n) [n]: 

A Makefile and a Windows command file can be generated for you so that you
only have to run e.g. `make html' instead of invoking sphinx-build
> Create Makefile? (y/n) [y]: 
> Create Windows command file? (y/n) [y]: n

Creating file ./docs/
Creating file ./docs/index.rst.
Creating file ./docs/Makefile.

Finished: An initial directory structure has been created.

You should now populate your master file ./docs/index.rst and create other documentation
source files. Use the Makefile to build the docs, like so:
   make builder
where "builder" is one of the supported builders, e.g. html, latex or linkcheck.

Upon completion, a docs file should appear in your project.

Generate HTML Documentation

You can then generate documentation in HTML format by changing to the docs folder and running the following command:

make html

You should see something like:

Running Sphinx v1.6.1
making output directory...
loading pickled environment... not yet created
loading intersphinx inventory from
intersphinx inventory has moved: ->

build succeeded.

Build finished. The HTML pages are in _build/html.

Document Project Modules

Now we will tell Sphinx to document the modules of one of our applications.

Open docs/

After the first block of comments, add the following code so that Sphinx can read docstrings from project files:

import os
import sys
import django
sys.path.insert(0, os.path.abspath('..'))
os.environ['DJANGO_SETTINGS_MODULE'] = 'yourprojectname.settings'

Next, create a modules folder within docs. We will use these to hold our documentation. E.g. To document models, create a file at modules/models.rst.

Edit models.rst and add the following content:

.. automodule:: yourappname.models

Save and close the file.

Next, make this link available in the documentation index by editing docs/index.rst.

Find the section starting with .. toctree:: and add a line modules/models under it so that it looks like this:

.. toctree::
   :maxdepth: 2
   :caption: Contents:


Save and close the file.

Now is the time to regenerate the documentation.

Run the following command from inside the docs folder.

make html

You can access the documentation by opening docs/_build/html/index.html in a browser. You should see ‘Models’ under ‘Content’.

That’s it!

If you want to be able to access your documentation from the Django application itself, e.g. using a link like /docs/, you can do this using the awesome django-docs package.
