Key Relationships: Parallel, Closely Related, and Distantly Related Keys - The Fun (and Musical) Guide 🎶
Introduction
Hey there, future Beethoven! Ready to unlock the secrets of key relationships in music? Whether you’re a Mozart in the making or think that a "circle of fifths" is a new dance craze, this guide is here to make learning about key relationships both fun and enlightening. 🎼
Parallel Keys: The Musical Twins 👯♂️
Parallel keys are like those twin friends who dress differently but secretly finish each other’s sentences. These keys share the same tonic (root pitch) but differ in their modes. For instance, C major and C minor both start with C, but they part ways from there. Major keys have a sunny disposition (think cheerful ice cream party 🎉) while minor keys prefer long, moody walks on the beach (cue the dramatic movie trailer music).
Another pair of parallel keys are the Dorian and Mixolydian modes. They share the same tonic but offer different vibes: Dorian has a cool minor tone with a zest of brightness, whereas Mixolydian likes to party with its dominant feel. Don’t worry if you’re not best friends with these modes yet, we'll get to know them better in Unit 8.
Parallel keys are fantastic for creating transitions and musical contrast. Imagine a song that goes from a bright, happy chorus in a major key to a soulful, introspective verse in the parallel minor key. It’s like the musical equivalent of changing from a rainbow shirt to a deep blue sweater – same you, different feel.
Closely related keys are the friendly neighbors who you can borrow a cup of sugar from at any time. These keys are harmonically similar, meaning they share many of the same pitches and make smooth transitions like butter. Nielsen's Law of Gummy Bear Sharing totally applies here.
Types of closely related keys include:
- Relative keys: These keys share the same key signature but have different tonics. Think of it like siblings with the same last name but different first names. C major and A minor, for instance, are relative keys.
- Dominant and subdominant keys: These keys are like best friends who live just a block away, a perfect fifth apart. For C major, the key of G (dominant) and the key of F (subdominant) fit this category.
- Tonic and dominant keys: These keys are a perfect fourth apart. So, Bb is the tonic key for F major, while F is the dominant key for Bb major.
To find closely related keys, take a spin around the circle of fifths. Each key has five closely related keys, including its relative minor, and the keys on either side of it with their respective relative minors.
Distantly related keys are the quirky relatives who make family gatherings interesting. These keys don’t share many harmonic traits, making their transitions more noticeable and intriguing.
Examples include:
- Tritone keys: These keys are six half steps apart and share no pitches. Imagine C and F# meeting each other like long-lost relatives at a reunion. Awkward at first, but interesting.
- Major second keys: Two half steps apart with just one pitch in common, like C and D figuring out how they're related.
- Major sixth keys: Nine half steps apart with only one shared pitch. It’s like C and A meeting unexpectedly at an event – different walks of life but a shared connection.
Using distantly related keys can build dramatic tension in your music. It’s like adding an unexpected plot twist to your favorite TV show – keeps everyone on their toes.
Introduction to Modulation: The Magic Key Change 🔑
Modulation is the art of changing keys in music – it’s like turning the page to a new chapter in a book. Composers use modulation to keep things fresh, create emotional shifts, and surprise the listener.
Modulating to Closely Related Keys: This creates a sense of continuity, like smoothly adjusting your rearview mirror while driving.
Modulating to Distantly Related Keys: Want to sound like Rachmaninov and surprise your audience? Modulating to distantly related keys adds a punch of dissonance and tension – perfect for those emotional rollercoaster pieces. But fair warning, it’s like learning to juggle – get the basics down first!
Key Terms to Review (And Sound Smart at Parties) 🥳
- Circle of Fifths: A visual map of all 12 major and minor keys, arranged in a circle by their perfect fifths relationships. It’s your GPS for navigating key signatures!
- Dominant Key: The key built on the fifth scale degree of a major or minor scale, creating tension that begs for resolution back to the tonic key.
- Dorian Mode: A minor scale that raises the pitch of the sixth degree, making it sound "half happy."
- Major Second: A spicy interval of two half steps, introducing just a pinch of adventure.
- Major Sixth: An interval of nine half steps—a long-distance relationship if ever there was one.
- Modulation: Shifting gears from one key to another in a song, spicing things up musically.
- Parallel Keys: Keys with the same starting point but different paths, like C major and C minor.
- Scale Degrees: Individual notes of a scale, numbered I through VII (probably wearing Roman sandals).
- Tritone: An interval so dissonant it splits your musical comfort zone right in two, like instant plot tension.
