INSTRUMENTAL INQUISITION
Guitar instrumentals have provided some of music’s most exciting moments. This month, as his progressive metal outfit releases a new album, Circadian, Jason Sidwell caught up with Intervals’s guitarist Aaron Marshall.
Aaron Marshall of Toronto proggers, Intervals.
GT: What is it about guitar instrumentals that appeals?
AM: I love the guitar, but I also love all music in general. So I suppose my passion for guitar-driven music is a product of wanting to compose and complete fully realised pieces that don't rely on another element to feel complete. It's not a preference, but perhaps born of necessity, rather. I like knowing that I can paint on the canvas without limitation, or compromise.
GT: What do you think an instrumental can provide a listener that a vocal song can't?
AM: There is certainly more room left for interpretation from the perspective of the listener. Instrumental music doesn't pander politically, religiously, or even emotionally from an explicit standpoint. Music itself is a universal language that is subjective and I think there is something very special about that.
GT: Any tendencies that you aim to embrace or avoid - rhythms, harmony, approach, tones?
AM: Aspects I embrace are the intuitive use of themes and motifs. I used to fight these, but the more I write songs, the more I realise those things happen for a reason. I think they can become the hallmark, or signature, for artists in this space, and I really enjoy being able to link varying compositions through this method. A tactile use of repetition in general is something I wholeheartedly embrace, counterweighted by decisive variation, or embellishment, of course. I'm not sure there is much I actively avoid, as I'm trying to be more in tune with my intuition. I'm not sure deliberately avoiding anything is productive, aside from a deliberate use of omission or limitation as a writing tool. But that's more at a micro level, versus the macro perspective.
GT: Is a typical song structure - intro, verse, chorus, etc - always relevant for an instrumental?
AM: I don't think it's always relevant but it certainly works best for me. Some semblance of traditional structure allows me to draw a straight line through my ideas and create pieces that are book ended, and tell a concise story. The through-composed approach certainly works for some artists, and I'm tempted at times, but I seem to find myself gravitating towards a relative framework, typically. Structure has no bearing on the content of a composition though, only how it moves.
GT: How useful is studying a vocalist's approach for creating or playing guitar melodies?
AM: Very useful, and often overlooked! I find myself to be melodically inspired the most by vocalists. There is a mindset and approach that allows you to deliver a melody on the guitar in a much different way if you think about how the voice functions, versus all of the opportunities and distractions that exist within the guitar. The same applies to all other instruments, like woodwinds, brass, piano, etc...
GT: How do you start writing one; is there a typical approach or inspiration for you?
AM: More often than not, an idea is the product of jamming and exploring freely, with no preconceptions. Then my intuition allows me to curate ideas, and zoom in to examine them further if I've found something that I know I can expand on further.
GT: What do you aim for when your performance is centre stage as with an instrumental?
AM: I aim to tell a story, just as any instrumental with a focal roll is meant to. I feel like I trade the additional dimension of lyrics, for the ability to shift between a melodic and vocal approach to lines that I want to stick with the listener, and then into phrasing and approaches that are exclusive to the electric guitar. I don't ever feel stuck, and I am able to continue telling the story with nuance and intrigue, or with vigour and intensity.
GT: Many vocal songs feature a solo that starts low and slow then finishes high and fast. Is this useful for instrumental writing, in developing pace and dynamics?
AM: The concept of dynamic and contrast is crucial to music in general, whether we're talking about how something develops over the course of a solo, or over the course of an entire song. There is certainly a time and place to come in guns blazing, if that is the desired vibe, but more often than not, taking time to build something, and always leaving a little extra gas in the tank, is much more musical and interesting overall.
GT: What type of guitar tone do you prefer for instrumentals?
AM: This is definitely dependent on the mood or emotion of a given piece of music. I like and utilise everything from full-tilt gain, to crystal clean.The music is what determines this.
GT: Favourite keys or tempos?
AM: There are certainly particular keys that provide more opportunities on the instrument based on how it's tuned. But I can't say I favour one over any others. I tend to let intuition determine this based on whatever it is that I'm working with. Same with tempo. There is a sweet spot for everything, it just depends on how closely you are listening.
GT: Do you find Minor or Major keys easier to write in?
AM: I don't find one easier than the other, no. This is largely dependent on perspective though; your fretboard knowledge will be what determines how you navigate, or what lens you are viewing through.
GT: And what about modes? Do you have any favourites?
AM: I try to be open to whatever the music I'm working on requires. But if I had to choose something, I'd say I'm probably a Lydian junky, haha.
GT: What about modulations into new keys?
AM: Certainly appropriate if the progression or tune calls for it.
GT: Do you view the backing band differently than you would when performing a vocal number?
AM: I don't, and I think this is what makes a difference in a lot of instrumental guitar music. I like an interactive approach to composing the backdrop for a song, where I leave myself sub melodies, and lines, or other opportunities for my lead guitars to chime in and out, through unison, or in harmony. When I am composing, I'm not actually thinking of the rest of the instrumentation as ‘the backing band’, and I think this is where the train comes off the rails with a lot of guitar-driven music. I am focused on composing music overall, and not just thinking about something the other instruments can do while I exercise chops. Ninety-five percent of the time, I leave all of my lead work until last, and then I bounce around and tweak moments so that everything serves a symbiotic purpose, equating in a song, rather than just a backing track with guitar on it. I truly feel that this is where a lot of guitar players lose the plot with music, in this space.
GT: What do you feel about harmonising melodies?
AM: Harmony and embellishment is a useful tool and effective where necessary. These days, I'm listening for where it is most necessary, rather than ‘let's harmonise everything!’ I also listen intently for non-linear harmony that supports a given line the way you would sing a melody, versus the obvious straight 3rds above or below.
GT: And what three guitar instrumentals do you consider iconic, or have inspired you?
Still Hurts by Marco Sfogli is a huge tune. This may very well be one of, if not, the first song I heard by Marco and it contains all the things I love about his playing and writing. Insanely melodic and tasteful, but also some wild lines peppered in throughout. So good! For Andy Timmons, I'd have to go with Electric Gypsy. This is just such an iconic tune, and I'd choose this for the same reason as my previous choice. This tune contains all of Andy's signature vibes and the tone is to die for! Lastly, from Greg Howe, I'd go with Child's Play from his Sound Proof record. Tons of pocket, poignant melodies, and some mind-bending lines, like all of Greg's stuff. I also love the octave motif he plays in the verses, along with the main theme the chorus is built around. Such a fun tune!
