Michael Oesterle’s music has been commissioned and performed by Canadian and European orchestras, ensembles, singers and soloists. This album is dedicated to three of Michael’s extraordinary works for solo instruments. Aventa’s solo flutist, Mark Takeshi McGregor, writes “here is a composer who understands the complexities and subtleties of writing for an unaccompanied instrument; who can reference the instrument’s incredibly rich history of both hedonistic folk music and 18th-century polyphony, all the while cunningly maintaining his unique voice.”
Alan Turing rode his bicycle.
He rode his bicycle to work.
He rode to Bletchley Park.
Riding, the chain on his bicycle comes off.
He rode his bicycle, counting – until the chain came off.
He rode his bicycle, counting.
Counting, he stopped before the chain came off.
He fixed the chain.
Riding again, counting,
he rode his bicycle to Bletchley Park.
Alan Turing (1912-1954) was a British mathematician, logician, cryptanalyst, philosopher, computer scientist, mathematical biologist, and marathon and ultra distance runner. In 2012, Turing’s 1944 reports on his “speech system” Delilah, were finally pulled from the British National Archives and opened to the public. This functional machine, designed to scramble and descramble voice messages, was so far ahead of its time that it resembles the way we currently store music in digital format.
The musical construction of Delilah for solo flute (2014) was motivated by Turing’s unorthodox search for humanity or human intelligence within patterns and systems. It uses modules within a scheme of triangular number sequences, applied to a metric grid of constant alternation between two and three. The music constantly resets, like the chain on Turing’s bicycle (one of the stories of Turing’s eccentricities related by his colleagues at Bletchley Park – headquarters of the code-breaking brain trust for Britain in WW II). It searches for answers to an unasked question, allowing this systematic approach to creating subtle emotional shifts. Like Turing, it presents its puzzle playfully: in its persistence, it becomes serious and then, as it begins to wallow in the process itself, lightens its mood again: a simple arc in a pattern of system, method, and discovery, its greatest motivation – the joy of moving forward.

“Stand Still for solo violin(2011) is a monologue of brooding nostalgia with flashes of virtuosic impudence. Over four short movements, the violin’s open strings resonate with a harmonic image that acts as a focal point around which the musical ideas pivot and play … there are hints of the Baroque, Folkloric, and Romantic traditions, snippets of diverse expressions which are all about my love for the instrument.
I had a close look at Westhoff, Guillemain and Bjarne Brustad solo violin scores, and I listened to recordings of my favourite violinist playing Bach. All of this set a context for my new piece, and writing the notes on the page wasn’t difficult – it all came together very quickly.” – Michael Oesterle
In his introduction to Spanning Tree (2013/14) Michael writes “A tree grows toward the sun, spanning the distance between itself and the light – each branch, each new angle reaching forward. In mathematics, the branches of the spanning tree never grow back on themselves, never interfere with the light or each other, or, more accurately: A tree is a connected undirected graph with no cycles. It is a spanning tree of a graph if it includes every vertex (every corner) of the graph and every edge in the tree belongs to it. In reality (or art), the branches may not be straight, they might just sustain themselves beyond supportability, endure past simple logic or usefulness, exceeding the limits of prescribed space and ownership, straining to become something new.”
“In this piece, the growth of the tree is the labour of a lone percussionist. The parameters for the development of the “tree” are distilled into a simple format – balancing sounds that are long and sustain effortlessly with sounds that are short and have minimal sustainability. In each cycle, the ratio of instruments that sustain, to instruments that support a clean attack, is even: moving through 1:1, 2:2, 3:3, 4:4, 5:5, and 6:6. The ordering of the six parts is up to the performer, as is the choice of the instruments and their combination. The six stages are not designed to evolve from simple to complex, but instead, they outline musical tableaux which are presented to the performer in the form of six maze-like graphs. The way that the points of the graph are connected is determined by the percussionist. The choice of instruments renders duets of long and short sounds forming paths that lead us through, or perhaps, keep us trapped in the maze.” – Michael Oesterle
Spanning Tree was commissioned by Daniel Cooper for percussionist David Schotzko.
