“It is the act of people being together, and finding that space together that I find most fascinating, and it’s the most difficult thing, I feel like I’m still learning how to do that and will be trying to do that for the rest of my life”. In this week’s episode, Marina and Madison speak with Catherine Lamb about her extensive practice of composing and performing in rational intonation, Erv Wilson’s proof of the harmonic series as a spiral, the process of tuning in as an expression of human agency in performance. We also talk about paradoxical roles of tones, her string quartet divisio spiralis, the Harmonic Space Orchestra, and tips for performers who are interested in deepening their relationship with rational intonation. The music at the beginning and end of this episode is from "divisio spiralis," performed by the JACK Quartet, from their 2021 album CATHERINE LAMB: String Quartets (Kairos) The music in the middle of the episode is an excerpt from "three bodies moving" from the 2019 album of the same name (Another Timbre), performed by Erika Duke-Kirkpatrick - cello; Eric km Clark - violin; and Phil O'Connor - bass clarinet For more information about Catherine Lamb, you can visit her website: https://www.sacredrealism.org/artists/catherine-lamb/
