In February 2019, the Australian OTO hosted "Music, Magick, & the Muse," an event featuring the distinguished Australian violinist, Tor Fromyhr, performing Leila’s score Θελημα: A Tone Testament.
The score - her only known composition - ran as a chapter in The Equinox Volume 1(8), published in Autumn 1912. The chapter includes a poem by Aleister Crowley and the below photograph of Leila Waddell.

Tor reflected on Leila’s skill as a violinist, remarking that she had undoubtedly endured the rigorous demands of the craft, mastering technique and approaching scales with the same diligence as any accomplished performer. "There's no compromising in her as a violinist," he noted.
​​
Regarding the composition, Tor observed, "I couldn't find a clear purpose for the piece or why it might have been written, unless it was part of an event involving extensive improvisation within fairly standard tonalities." He speculated that it was likely a single piece from a larger suite of improvisations, with this segment chosen for notation. "The piece is harmonically traditional," he added, "reflecting mid-Romantic style - much in the vein of Wieniawski, but more influenced by Bach and Paganini."​​

The photograph was taken by Dover Street Studios, a renowned establishment in Westminster specializing in theatrical portraiture. Notably, Leila appears nude, seated in profile, holding what seems to be an oriental or magical mirror. The meaning of this imagery remains open to interpretation; magic mirrors, rich in symbolism, have long been significant in rituals and spiritual practices.
