On Flavors, Tastes, Sound And Perception: Thinking Through Ruhlman’s Twenty

by Thomas Brett

“Clear your way. Always be thinking.” - Michael Ruhlman, Ruhlman’s Twenty

First, let me say the obvious: if you like to cook and want to know more about the science and craft of cooking, you’ll probably enjoy Michael Ruhlman’s Ruhlman’s Twenty. The book provides much to think about by explaining fundamental techniques and ingredients in a sensible and accessible way. Having said the obvious, there are other interesting things happening in Ruhlman’s Twenty. In the midst of the cooking theory, tips, instruction, and recipes, Ruhlman spends a fair amount of time talking about taste perception. Here are two examples:

“The complexity that comes from the intense sourness offset by a parallel sweetness goes especially well with…” (100).

“Does this sauce have the depth of texture and satisfying nature that I’m after? If not, fat may be the solution” (134).

Complexity. Sourness. Sweetness. Depth of texture. The overarching theme of this book is how we create and perceive specific tastes, and Ruhlman wants us to “always be thinking” about what affects what in the alchemical world of the kitchen. As it turns out, in the world of cooking, everything affects everything else. In the chapter “Acid” Ruhlman writes: “When you taste anything, ask yourself, What would make this better? Often the answer is acid.” He then discusses the effects of adding a drop of vinegar to a spoonful of soup. Ruhlman describes the taste as brighter: “Bright is an element of flavor that takes some imagination. I don’t mean literally brighter, but synesthetically brighter: vinegar has a brighter flavor–clear, clean, crisp” (92). Similar discussions ensue in chapters on salt, sweetness, and other tastes.

In the end, cooks work with essentially six distinct tastes: sweet, salty, sour, bitter, metallic, and umami–a Japanese word that roughly means “savoriness.” And while it may be difficult to put into words what these different tastes do and the complex ways they interact with one another, good cooking can’t happen without their presence in various ratios. Think about a favorite daily sauce: vinaigrette. Oil (fatty umami), vinegar or lemon juice (sharp sourness), a pinch of salt (saltiness), and maybe some honey (sweetness). That’s four of the six essential flavor components. No wonder salad is so tasty!


As in cooking, so too in music?

Just as food presents us with a range of tastes, music presents us with a range of heard and felt vibratory perceptions. In music, we speak of low-, medium-, and high-range pitches or registers. Low-pitched sounds vibrate at a slower rate than do high-pitched sounds. Moreover, low-pitched sounds are often considered to have a “dark” tone quality or timbre (think of a low note bowed on a double bass, or the sound of a deep gong softly struck) while high-pitched sounds have a “light” quality–or like Ruhlman’s vinegar taste, are “brighter” (think of a shrill piccolo sound). A musical instrument’s design, its mode of vibration, and the material it’s made out of also affect its timbre. It’s for this reason that a flute and a violin sound different and distinctive even when they play the same pitch. When composers score works for different instruments (violins and brass say, or electronic sine tones and pad sounds) they create new hybrid timbres that are more than the sum of their parts. In music as in cooking, one can mix and match to create new depths of perception.

I’ve been thinking about Ruhlman’s book as I’ve been working on some electronic music pieces. I’m in the mixing and balancing stages of a project, listening through to make sure all the sounds are sitting in the right proportion to one another to create a pleasing soundscape. As I listen it strikes me that sounds are like flavors–each one has a different taste. I don’t mean to say that there are six basic sounds that correspond to sweet, salty, and so on. But I do mean to say that different sounds, like different flavors, affect us in many different ways. Put another way, sounds have a feeling dimension just as flavors have a taste dimension.

The five electronic music pieces in my project each have over a dozen parts–including marimba samples, sine tones, Rhodes, glockenspiel and celeste, tom toms and cymbals.  There are a lot of layers and each layer has a distinctive pitch register and timbre profile. The parts were improvised and recorded many months ago: chord progressions were worked out, harmonies, basslines, and rhythmic counterpoint among the percussion added. Then everything was put into order so the pieces have a basic arc shape (each is some 20-plus minutes in length). Now I’m experimenting with different combinations of these layers, tweaking their volume, their tone, their pitch, and adding bits of delay and reverb effects to augment and change them. It’s a lot to think about and the possibilities for tweaking can feel endless.

But like Ruhlman’s story about the effect of a drop of vinegar on the taste of a spoonful of soup, I’m finding that small changes can have large effects on the overall feel of the music. For instance, tuning tom-toms to the tonic note of a section adds a deep euphony. Or pitching a hi hat sample up one octave makes it feel more metallic, crisp and brittle. Or maybe one part needs an EQ scoop (lowering the volume of its middle-range frequencies) to make it flatter, softer, and more transparent. Of course, the sound really isn’t any of those things–it’s basically a sawtooth wave sound–yet that’s how it feels as I listen and so I adjust parameters according to this imagined profile. All this tweaking is done intuitively, until the sound of the music feels right.

Finally, I’m surprised at how different the pieces sound as I return to them day after day. Same headphone volume, but a slightly different listening me, I guess. Taste is like that: it’s not entirely in the flavor, the ingredient, or the sound, but neither is it entirely in our perception of these phenomena either. It’s a combination of the two and that’s what makes the intersection of flavor, taste, and perception so interesting: it’s an unstable and ever-changing encounter for our senses.
