Album Notes
OHAMA: "Tower - Trees"
Part of the 28th Annual High Performance Rodeo in Calgary, Alberta, Canada
January 2014
Artist Statement:
The Calgary Tower Carillon Celebration is an interactive multiambient composition performed in Calgary's Downtown Core as part of the 2014 High Performance Rodeo.

As we go about our days in The City of Calgary's downtown, known simply as "The Core", we can grow so accustomed to the sounds around us that we simply blank them out. The Core is a mixture of continuous and varying sound: C-trains accelerating and decelerating, general traffic, crosswalk beeps and sirens, pedestrian footsteps and conversations, distant construction, not to mention more natural sounds like birds and wind and just the ambient sound of winter air.

The piece I've composed has 3 important elements: The Calgary Tower Carillon, the Calgary Core environment and the Trees Sculpture on Stephen Avenue.

First, I wanted to stay within the limitations of an actual carillon instrument. Although the Calgary Tower Carillon is played with a two-register organ-style keyboard, traditionally carillons are played by striking levers with your fists. Specifically I did not want to treat the carillon as a keyboard instrument, but as a group of large physical bells being struck one by one. I don't think carillon music should be dense, full of chords or complex melodies and harmonies. I believe it should be sparse so that you can clearly hear the ringing of the individual bells.

Secondly I realized the instrument is heard in the outside world where one has no control over the environment. At any instant, a bus may drive past you in the Core and drown out the sound of the bells. Obviously all those sounds are part of the instrument, as are the echos and reverberation of the bells against the tall city structures. The bells are just one part of the overall aural environment of the Core.

The third and final element was "Trees", inspired by the structures outside Bankers Hall on Stephen Avenue. I recorded 10 tracks of synthetic electronic music for each of the 10 trees, evoking images of wind blowing through the structures and reflecting the subtle deflections and deformations under load. "Trees" is designed to be played at a low volume on headphones to mix simultaneously with live "Core" and "Tower" sounds.

I have no control over the mix of any of the elements, so each performance will be unique depending on where you are and and where you move. I also consider your attention level part of the composition, so each performance will be unique depending on who you are and what you hear.

I hope that by listening to "Tower - Trees" you achieve aural-satori and you feel more a part of Calgary's Core as you move through your daily life.

Download any or all of the 10 tracks to yourPod device. My personal favorites are tracks B and D. Play back the tracks while walking in the Core. Turn the volume low so you can hear the distant Calgary Tower Carillon bells and the ambient city noise.

The bells will be playing daily at 12 noon.

Also remember all the sounds of the Core are meant to be a part of the composition - random cars, walk/don't walk beacons, C-Trains and buses, automobiles driving by, magpies squawking or honking horns. I encourage everyone to hear and listen.

The "Trees" music is a bed upon which all else sits, so do not worry if it fades in and out. It is not designed to be constantly above the level of the ambient environment in this context.

I hope you enjoy this large environmental piece of music. And although you cannot hear it, imagine the breeze as it flows through the "Trees" installation when you listen to the music.
NOTE: After the HPR, "Trees" will continue to be a free download, for use with the album "Multiambient Tower Soundscape".
More information about "Trees" here:

"The ten tree sculptures located north of the west tower of Bankers Hall, on Stephen Avenue, are a gift from Trizec Hahn Office Properties to the City of Calgary, made in 2000 following the completion of the second Bankers Hall office building."

"...the trunk elements are two rectangular box sections and one triangular box section, all of which taper to a smaller cross section as the leg like elements rise to the tops of the trees. Approximately at the mid height of each sculpture type, the triangular box leg is divided into two rectangular box legs which continue to taper as they rise higher in the trees. Both design types have four levels of horizontal bracing incorporated into the designs, and all of the box leg sections have internal 10 mm thick stiffener plates at 750 mm centers welded to the inside of the box section plates, which presented a significant challenge to the Fabricator. The leaf elements are 300 mm deep by 121 mm wide channel like sections cold formed from 10 gauge steel plate.

All of the structural steel conforms to CSA G40.20/G40.21 grade 350W. Welding conforms to CSA W49, with all exposed welds being ground smooth to the Architect’s satisfaction.

At the time of structural design, a finite element analysis program was not readily available, therefore, at 300 mm vertical intervals, cross sections of the elements of the structure were modelled employing the Soda program to structurally analyse the sculpture, so as to design the appropriate wall thickness of the box sections and determine deflections and deformations."
