What are Messiaen's Modes of Limited Transposition? - Music Theory
TLDRIn this video, Gareth Green provides an in-depth look at French composer Olivier Messiaen's modes of limited transposition - a system of scales with a limited number of possible transpositions before repeating themselves. Green analyzes each of Messiaen's 7 modes, examining their interval patterns, groups of notes within the modes, number of possible transpositions, and how they relate to Messiaen's musical influences like Debussy. The goal is to give viewers a deeper understanding of these unique scales Messiaen used as his compositional building blocks, allowing them to better appreciate his music or try composing their own pieces using these modes.
Takeaways
- 😀 Messiaen developed unique 'modes of limited transposition' as an alternative to traditional major/minor tonality
- 👂 These modes have a distinctive sound and can only be transposed a limited number of times before repeating
- 🎹 The modes feature symmetrical patterns of whole steps and half steps organized into groups
- 🔢 There are 7 modes total, each with a different number of possible transpositions
- 🎵 The 1st mode is a whole tone scale with 2 possible transpositions
- ♫ The 2nd mode is called the Octatonic scale and has 3 possible transpositions
- 🎼 Modes 3-7 have increasing complexity and more chromaticism
- 🎤 Messiaen was influenced by nature, bird songs, Indian ragas and Debussy's impressionism
- 🎚 His music moves away from strict 12-tone serialism towards more freedom
- 💡 Understanding Messiaen's modes allows deeper appreciation and can aid composers in writing music
Q & A
What are Messiaen's modes of limited transposition?
-Messiaen's modes of limited transposition are scales that he devised which have a limited number of possible transpositions before the sequence of intervals repeats itself.
Why did Messiaen create these new modes?
-Messiaen wanted to find new systems for composing music, rather than following the serialist techniques used by composers like Schoenberg. He wanted more freedom than strict serialism allowed.
What is meant by 'limited transposition'?
-A mode has limited transposition if you can only transpose it a certain number of times before the sequence of intervals repeats itself, which is different than a traditional major or minor scale.
How many modes of limited transposition did Messiaen create?
-Messiaen created 7 different modes of limited transposition.
What influences did Messiaen draw upon?
-Messiaen had influences from diverse sources including bird song, Indian raga rhythms, and the impressionist composers like Debussy who experimented with different scales and non-Western music.
How are the modes constructed?
-The modes follow particular patterns of whole steps and half steps or tones and semitones. They are arranged into groups that repeat the same intervallic patterns.
What is the first mode?
-The first mode is the whole tone scale, which has only two possible transpositions.
How many notes are in the fifth mode?
-The fifth mode contains only 6 notes - it has wider gaps between notes including major thirds.
What intervallic pattern makes up the seventh mode?
-The seventh mode follows a chromatic pattern with lots of semitones, including between C-Dflat, Dflat-D, D-Eflat. There is only one whole step between Eflat and F in each group.
What is the purpose of introducing these modes?
-The goal is to allow musicians to understand Messiaen's compositional style and also to facilitate composing or analyzing music using his modes as a basis.
Outlines
😀 Introduction to Olivier Messiaen's modes of limited transposition
This paragraph provides background on 20th century French composer Olivier Messiaen, describing his diverse influences like bird songs and Indian ragas. It introduces his innovative system called 'modes of limited transposition' which he developed as an alternative to 12-tone serialism.
😯 Explaining limited transpositions through Messiaen's first and second modes
This explains the principle of limited transpositions through the first 'whole tone' mode. It has only 2 possible transpositions before repeating. The second 'octatonic' mode with alternating tones and semitones has 3 possible transpositions, conceived as 4 groups of 3 notes.
😃 More chromatic third mode and two-grouped fourth mode
The third mode has 4 possible transpositions with more semitones, conceived as 3 groups of 4 notes having the same tone-semitone pattern. The fourth mode has 2 repeated tone-semitone groups allowing 6 transpositions.
🤔 Modes five to seven showing evolving patterns
The fifth mode has wider gaps like major thirds and 2 groups of 4 notes. The sixth mode feels less radical with 6 transpositions and 2 groups. The seventh mode is chromatic again with close semitone movements and 6 transpositions over 2 groups.

Highlights
Messiaen developed his own unique modes of limited transposition that serve as the basis for much of his music.
Messiaen was inspired by Debussy's use of different scales and non-Western influences, but wanted to find his own system.
The modes have a limited number of possible transpositions before you return back to the original.
The first mode is a whole tone scale with only two possible transpositions.
The second mode is called the Octatonic scale with three possible transpositions.
The third mode has four possible transpositions and more chromaticism.
The fourth mode introduces intervals of a third between notes.
The fifth mode also has intervals of a third and fewer notes.
The sixth mode starts off like the major scale before taking a different direction.
The seventh mode is the most compact and chromatic of the modes.
Understanding the modes helps appreciate Messiaen's style and system.
The video explains the basic concept of limited transposition.
The groups show how patterns of tones and semitones repeat.
