Description
Living in Arizona means developing an active awareness of how heat shapes our daily lives. in Phoenix, the average daily temperature in July (the hottest month of the year) hovers around 95.5°F (35.3°C), with record highs reaching 122°F (50°C). The average daily maximum in July is 106.5°F (41.4°C), making heat not just a condition but a constant presence.
What we often overlook, however, are the residents who lack access to reliable transportation. Spanning over 1,100 square miles, the Phoenix metropolitan area is one of the largest examples of urban sprawl in the United States. While Valley Metro provides transit across much of this region, weekday ridership averages only about 126,700 or roughly 3.5% of the population. Limited route coverage, infrequent service (with many buses arriving only every 20 minutes), and the unbearable nature of waiting in 110°F (43°C) heat contribute to this low usage.
The result is a disproportionate burden on lower-income individuals, many of whom rely on these limited transit systems for work, education, and access to basic needs. Heat Index is in dialogue with the efforts of Arizona based landscape architects and urban planners who are working to mitigate this harm through the strategic use of shade, trees, and thoughtful redesign of public infrastructure. The work reflects both the oppressive weight of the desert heat and the human resilience required to move through it.
Publishers use a lot of words to describe what they sell, and we know it can be confusing. We've tried to be as clear as possible to make sure you get exactly what you are looking for. Below are descriptions of the terms that we use to describe the various formats that music often comes in.
Choral Score
A score for vocalists that only contains the vocal lines. The instrumental parts are not there for reference. Generally, cheaper than a vocal score and requires multiple copies for purchase.
Facsimile
Reproductions of the original hand-written scores from the composer.
Full Score
For ensemble music, this indicates that the edition contains all parts on a single system (there are not separate parts for each player). In larger ensembles, this is for the conductor.
Hardcover
Hardbound. Generally either linen-covered or half-leather.
Orchestral Parts
Similar to a wind set, this is a collection of parts. In the case of strings, the numbers listed are the number of copies included, though generally these are available individually (often with minimum quantities required).
Paperback
When publishers offer multiple bindings (e.g. hardcover) or study scores, this is the "standard" version. If you're planning to play the music, this is probably what you want.
Performance / Playing Score
A score of the music containing all parts on one system, intended for players to share. There are not separate parts for each player.
Set of Parts
For ensemble music, this indicates that there are separate individual parts for each player.
Solo Part with Piano Reduction
For solo pieces with orchestra, this is a version that contains a piano reduction of the orchestra parts. For piano pieces, two copies are typically needed for performance.
Study Score
A small (think choral size) copy of the complete score meant for studying, and not playing. They make great add-ons when learning concertos and small chamber works.
Vocal Score
A score prepared for vocalists that includes the piano/organ part or a reduction of the instrumental parts.
Wind Set
For orchestral music, this is a collection of wind and percussion parts. The specific quantities of each instrument are notated.
With Audio
In addition to the printed music, the edition contains recordings of the pieces. This may be an included CD, or access to files on the internet.
With / Without Fingering (Markings)
Some publishers prepare two copies - a pure Urtext edition that includes no fingering (or bowing) suggestions and a lightly edited version that includes a minimal number of editorial markings.
