Welcome to our tutorial on composing a contrafact. A contrafact is a musical composition where you create a new melody using the chord progression of an existing song. In other words, you keep the same harmony but create a completely different tune. This technique has been widely used in jazz, where musicians often create new melodies over familiar chord progressions. In this example, you can see how the contrafact uses the same chord progression as the original tune, but with a different melody. In the following scenes, we'll break down the step-by-step process of creating your own contrafact.
Welcome to our guide on creating a contrafact in jazz. A contrafact is simply a new melody composed over an existing chord progression. This technique has been a cornerstone of jazz innovation, allowing musicians to create fresh musical statements while honoring the harmonic frameworks of established compositions. Famous examples include Charlie Parker's 'Ornithology' based on 'How High the Moon', Sonny Rollins' 'Oleo' based on 'I Got Rhythm', and Tadd Dameron's 'Hot House' based on 'What Is This Thing Called Love'. The key characteristics of a contrafact are that it uses the exact same chord progression as the source tune, features a completely new melody, and often introduces more complexity or faster tempos than the original composition.
The first step in creating a contrafact is to choose a source tune with a chord progression you like. Jazz standards like 'Autumn Leaves' are excellent choices, as are blues progressions or pop songs with clear harmonic structures. Once you've selected your source material, analyze the chord progression thoroughly. Identify the key signature and the form of the piece. In our example, 'Autumn Leaves' is in B-flat major or its relative minor, G minor, with a 32-bar AABA form. Next, understand the function of each chord within the key. Notice how the first three chords form a classic two-five-one progression. Also pay attention to the duration of each chord - how many beats or measures it lasts. This analysis provides the harmonic foundation upon which you'll build your new melody.
Now that you understand the chord progression, it's time to create a new melodic idea. Start by developing melody fragments using different approaches. One strategy is targeting chord tones, especially guide tones like the third and seventh, which define the chord quality. You can also use scale-based approaches, drawing from appropriate scales that fit each chord. Another effective technique is developing short melodic motifs and patterns that you can repeat and vary throughout your contrafact. As you compose, apply concepts like repetition with variation to create unity while maintaining interest. Think in terms of question and answer phrases to give your melody conversational qualities. And remember to create moments of tension followed by release, which is essential to musical storytelling. These approaches will help you craft a melody that's both cohesive and engaging.
With your initial melodic ideas in place, it's time to develop a complete melody for your contrafact. First, structure your melody to match the form of the original tune. If the source material has an AABA form, as many jazz standards do, maintain that structure in your contrafact. Create distinct sections that give your composition shape and direction. In the A sections, establish your main theme, perhaps with slight variations in repetitions. For the B section or bridge, introduce contrasting material that provides development. When returning to the final A section, consider adding a sense of finality or resolution. As you refine your melody, ensure it works well with each chord in the progression. Pay special attention to how your melody notes interact with the harmony, especially at chord changes. Add dynamics and articulations to bring your melody to life, and consider the overall contour of your melodic line to create a satisfying musical journey.
You've now reached the final step in creating your contrafact: polishing and practicing your composition. Take time to refine any difficult passages to ensure they're playable and effective. Consider adding an optional introduction or ending to frame your contrafact, though these aren't strictly necessary. Think carefully about the tempo and style - contrafacts are often played faster than their source material, but this is your artistic choice. When practicing your new composition, start slowly to build accuracy, then gradually increase the tempo. Recording yourself is invaluable for evaluation and improvement. Finally, share your contrafact with other musicians for feedback and collaborative performance opportunities. Throughout jazz history, many iconic compositions have been created through this process, such as Charlie Parker's 'Donna Lee' based on 'Indiana' and 'Moose the Mooche' based on 'I Got Rhythm'. By following these steps, you've now created your own contrafact - a new melody over an existing chord progression - continuing this rich jazz tradition.
