Here’s a comprehensive list of live classical music performances in Tucson for the year 2022 where the program of composers and works has been published. I will keep this Excel document regularly updated. Please post a comment if anything should be added or changed.
I’ve included a column called “Dave’s Faves” which notes the works I am already familiar with and that I highly recommend. This is subjective, of course, but I hope this will help some of you in deciding which concerts to attend.
Happy Listening!

If you live in the Tucson metro area and would like to get together each month to listen to and discuss recordings of favorite classical music pieces we love and would like to introduce to others, I hope you will consider joining:
In 2022, the best dates and times for observing the zodiacal light are listed in the calendar below. The sky must be very clear with little or no light pollution. The specific times listed are for Dodgeville, Wisconsin (42° 58′ N, 90° 08′ W).
Here’s a nicely-formatted printable PDF file of the zodiacal light calendar:
The best nights to observe the zodiacal light at mid-northern latitudes occur when the ecliptic plane intersects the horizon at an angle of 60° or steeper. The dates above were chosen on that basis, with the Sun at least 18° below the horizon and the Moon below the horizon being used to calculate the times. An interval of time of one hour either before morning twilight or after evening twilight was chosen arbitrarily because it is the “best one hour” for observing the zodiacal light. The zodiacal light cone will be brightest and will reach highest above the horizon when the Sun is 18° below the horizon (astronomical twilight), but no less.
If you are interested in calculating the angle the ecliptic makes with your horizon for any date and time, you can use the following formula:
where I is the angle between the ecliptic and the horizon, ε is the obliquity of the ecliptic, φ is the latitude of the observer, and θ is the local sidereal time (the right ascension of objects on the observer's meridian at the time of observation).
Here’s a SAS program I wrote to do these calculations:
