The Mind of a songwriter is often wired differently than that of a guitarist.
Though the two cross paths often, it's rare to see a pro-level guitar player (particularly a lead guitarist) and a successful songwriter embodying the same human being. But if you're that guitar player, the guy or gal whose expertise is wrapped up in solos, arpeggios and all the technical abilities thereof, how do you approach the songwriting process? What's your role?
If you're good, you'll find yourself getting invitations for session work and opportunities to contribute to other people's music. When that time comes, here's what your job description will entail.
1. To Increase the Originality of the Music
A chord progression by itself doesn't make a song.
In fact, there are only a few commonly used chord progressions for the most of the primary music genres and a ton of music that's derived from them.
The melody and layering, whether it comes from a vocalist or a guitar player, are the primary ways one piece of music can be differentiated from another. It makes music better by increasing the quality and originality of the end product.
When it comes to songwriting, it's your job to make sure you increase a song's quality by using melody and layering
2. To Add Melody and Melodic Accents
Melody is one of the most crucial parts of a lead guitarist's job description, especially when you're talking about songwriting. If you're working with a songwriter, they've likely already come up with the lyrics and a chord progression, so melody will build on that material.
Loosely, this is the process you'll follow:
- Learn the chord progression
- Memorize the melody of the lyric line
- Accent either or both with a secondary melody from your guitar
Though the more functional solution is to reference the chord progression. One of the simplest ways to do that is to create an arpeggiated version of the bass line. So keep in mind that anytime you're adding a short fill or a solo, you're creating some kind of melody.
In that instance you're sharing just as much responsibility as a vocalist. Thus it becomes more important for you to be musical, melodic and complimentary with your guitar than it does to be technical and fun to watch.
3. To Develop and Add Layering
Though it can involve melody, the practice of layering is an altogether different discipline and an equally important part of a guitar player's role in the songwriting process.
While contributing melody requires a certain level of creative input, layering is a matter of adding something to a vocal line or guitar track that's already in place. It can even be a guitar part you came up with.
Whatever the case may be, it's assumed you're layering over something that's already recorded. Layering can involve one or more of the following practices.
- Simply duplicating a chord progression or lead pattern
- Adding an effect layer to a chord progression or lead pattern
- Recording separate guitar tracks for the left and right channels
The details are largely up to the songwriter, though most people who hire a session guitarist will accept ideas and input in this area. If you've got session work in your future, reading up on layering guitars in the studio would be a practical way to prepare.
How to sum it all up?
If you had to condense the answer to this question, you might say your role is to invoke an emotional response from those who might listen to the music you're creating.
Adding melody, layering, effects and harmony are all about increasing the song's ability to appeal to someone's emotions.
That's your job, not just a guitar player, but as a musician.
