Not sure what you’d want to play, but curious about performing as a soloist? Please still reach out! We’re happy to talk through ideas and help identify repertoire that could be a good fit.

Member Guidelines
Please download and carefully read the HSO Member Guidelines. All orchestra members will be expected to know and follow our guidelines, or may be requested to not participate with us.
- Rehearsals start promptly at 7:00 p.m. Please be warmed up and seated at that time.
- Bring your own stand
- Please be patient when the conductor is working with another section.
- Music needs to be kept in the folder provided. Please be careful to keep the music in excellent condition, including working photocopies, limiting markings to pencil only.
- Music and photocopies must be returned upon completion of a performance or your departure from the group. Any damage or loss of music will result in a fine.
- Each rehearsal is an important opportunity for you to contribute to the overall sound of your section. Every effort in attending all rehearsals is appreciated.
- If you have an announcement or reminder that you would like to share with all members please send to secretary@hillsborosymphony.org
The concert dress code is black dressy, not casual. Each member should look professional, but not draw attention to themselves visually. Ideally, the music should be the focus of the audience’s attention, not the sight of the players. You may wear a white collared shirt if you wear a tux or suit jacket. Tuxes/suits are encouraged but not required. Otherwise, all clothing should be black (including ties, shoes, and socks). If you are not wearing a jacket, shirtsleeves should be at least short sleeves, no cap sleeves, sleeveless, or tank tops. Shirts should not be low-cut or show midriff. Pants should be slacks or other nice pants (no jeans or leggings, even if they are black); no capris or shorts. Dresses or skirts must reach below the knee. Black socks or stockings need to be worn; no bare legs or feet. Shoes should be black dress shoes, not athletic shoes or sneakers. Shoes that expose part of the foot (such as ballet slippers) should be worn with black socks or hose. Jewelry should be kept to a minimum.
In general, wear black and use your best judgment to dress nicely, look professional, and blend with the group.
Concert Dress:
HSO will follow the City's lead on masking, though you are welcome to continue wearing a mask if you choose. We continue, however, to ask everyone to stay home when you have any COVID/cold/flu symptoms to prevent the spread of germs.
HSO is resuming enforcement of the attendance policy. Full text is in our member guidelines on the members' page on our website. In short, if you miss more than three rehearsals per concert cycle (excused or unexcused), you will be asked to not play in the concert. Members shall be dropped from the roster after 4 unexcused absences in one year (September–May).
An absence is excused when the member notifies everyone below within 24 hours of rehearsal:
The board can make exceptions to the above policies. We understand that other things come up and want to work with you. Contact the board (board@hillsborosymphony.org) and tell us your situation. We are most likely to grant you an exception if you are giving us plenty of notice of your plans or if you are a member with a good history of attendance or participation.

Absense Policy:
The HSO librarian's job is to make sure you have the music you need to play your best. To that end, I also need help from you. So please:
Contact our librarian, Molly Kalmbach, at librarian@hillsborosymphony.org
- Use only a pencil in your parts so they can be cleaned for future HSO players. Please no pen or highlighter, or even excessively dark or large pencil markings, which can be hard to remove;
- Contact me before Friday if you need something by Monday's rehearsal. If you're missing something, need to double a part, or want help with a page turn, I will be happy to get you the music you need. If you ask for something on Friday or over the weekend, however, I may not be able to get to it; and
- Please take care of your folder and parts. Folders and parts can be very expensive and difficult to replace.
