Below are some of the day to day tools that I use in order to help keep myself organized.
When dealing with four concert groups, two at the high school and two at the intermediate, and a beginner class each year, it is really easy to lose track of who is playing what. Four groups doing an average of three pieces on three concerts a year is at least 36 pieces a year. To help keep track of who is playing what, I create a part assignment spreadsheet each year so that I can be sure that I'm assigning each student a variety of parts and so that I can figure out what they are playing when they forget.
I use a Google Sheets spreadsheet to track the percussion students attendance each marching season. This easy spreadsheet helps me keep accurate attendance for grades and allows me to go back after marching season to check students attendance when having drumline auditions.
We started to use this spreadsheet at beginner audition time to help balance out some of our sections once students get to the high school. We use the numbers per instrument per grade level to set a range of what we want for each instrument during beginner auditions with soft and hard caps.
These are the diagrams that I use to help plan for front ensemble setups. Each instrument is roughly to scale with each other. This allows me to see how wide each row will be in relation to each other without having to set up all the keyboards in a room. This also allows me to diagram out cable runs ahead of time without having to do trial and error. If there is a particularly complicated percussion ensemble concert setup, I will also use these diagrams in order to storyboard how to change from one piece/setup to the next.
