Polytonality: For Concerto/OrchestralWriting lesson

Please watch the video above for detailed analysis:

Hi Guys,

This is the Re-Post that you requested.

PART 1:

What is Polytonality?

Polytonality is the use of two or more keys at the same time:

Example 1:

Db Major/C Major [Basic root position]

poly-tonality-orchestral-composing-chords-example

In this first example we have 4 bars of Polytonality with Eminor/DbMajor and EbMajor/CMajor

Sheet music showing a polytonal example with E minor/Db Major and Eb Major/C Major labels. — Musical notation illustrating polytonality with E minor/Db Major and Eb Major/C Major.

This then resolves itself with a “Tonal” diatonic cadence of B7/D# to Em:

This method is really useful because we can use the polytonal approach sparingly with it’s thicker and richer harmonic texture whilst then then playing its opposite it with the thinner aspect of diatonicism.

This way the Polytonal nature of the music compliments the diatonic cadences and visa versa.

Example 2:

Polytonality-Orchestral Example

This example explores “Implication”. In this case it is implying the melodic minor but avoiding the cliche by employing the richness of Polytonality:

Sheet music showing C# minor, Fm7, A minor, Ab Major, and Gm6/A chords with annotations as examples for polytonality. — Musical notation illustrating chord progressions in polytonality, featuring C# minor, Fm7, Aminor, Ab Major, and Gm6/A.

From here, we will again employ diatonic harmony for a cadence.

To complete this short orchestral example we will go back into Polytonality with another melodic minor implication by employing Dminor/DbMajor:

Sheet music showing the chord labels 'D minor' and 'Db Major' in red text to demonstrate polytonality. — Musical chart depicting D minor and Db Major for a polytonal music example.

Here is the chart:

Example 3:

Polytonality-Orchestral Example

In this final example we will just “Reverse” the chords. This time it is DbMajor/Cmajor which is then played the other way around with CMajor/DbMajor.

finally, we will employ a slash chord for an “Implied” cadence: This will also lighten the harmony:

Musical notation of a slash chord labeled 'G/C' with staff lines and symbols. — Illustration of a G/C slash chord as notated in music theory.

Easier way to improvise with Music Modes [Guitar]

IMPORTANT: Please watch video above for detailed info:

Hi Guys,

Today, a quick look at another way of exploiting modes/improvisation on the guitar fingerboard.

We will be creating music via concepts/musical tools based on this minor shape.

Why do this?

Because with this 5 fret shape arpeggio we can easily create:

So, for instance in C Major [Ionian] we can take chord iii and Vi arpeggio shapes as a solid base and create/develop improvisation-as opposed to learning millions of scale/mode shapes/patterns etc.

With this as a base we can develop proper musical lines and rhythmic phrasing

Before we start it’s important to see how easily chords iii and Vi link together:

Example:

The first thing to be aware of is the basic pentatonic’s right under our fingertips with this arpeggio shape:

[These pentatonic’s give us some basic building blocks from the outset]:

QUARTAL SOUNDS

Next let’s add some 4ths for a Quartal jazz/fusion-esque sound:

Descending:

Ascending:

With extension

Basic Quartal fingerboard movement:

CYLE OF 4THS

Another thing to take into consideration is the cycle of 4ths under our fingertips:

Remember that we can also make these, major, minor, diminished or augmented:

For instance all major:

All minor

[This gives us even more colour and choices for chromaticism/chromatic movement right under our fingertips once again]

TARGET TONES/APPROACH NOTES [JAZZ CHROMATICS]

Below, we can see the set-up for target tones with this Em arpeggio shape:

We can also add some chromatic notes to this to create a longer jazzy-esque line:

String Skipping Petnatonic’s

String skipping works well because it removes familiarity/cliches from the ear:

Here are two examples:

Example 2:

PAIRING TRIADS

Lastly pairing triads works really. Here is a Lydian example:

conclusion

This blog has only really touched on this way of thinking, but, you can see how easy it is to make connecting lines and musical phrasing and how to exploit improvisation tools from this simple minor arpeggio shape.

How to play Shakti Indian Guitar Scales

Posted on May 8, 2025May 8, 2025 by Modern Music Theory and Application

Please watch video above for detailed info:

Hi Guys,

Today, a quick look at the first of a few Shakti Indian guitar scales for tabla and guitar improvisation.

The first one that we will look at today is the A Mixolydian Mode exploited in a pentatonic form.

“The guitar technique employed is strict alternate picking”.

A MIXOLYDIAN:

Here, is the basic scale ascending. The G natural gives the unique flavour and colour as it possesses the dominant sound, but, in a non resolving from.
