of the University of Michigan Lurie Carillon

Here you can download modal data of the University of Michigan Lurie Carillon. The data are provided in csv format. The data are published in several ways:

One-Bell-Per-File, Frequency-Sorted where each bell's data are in separate files. The columns are ordered FREQUENCY, AMPLITUDE, DECAY, PHASE, and each row corresponds to a different vibrational mode.

One-Bell-Per-File, Amplitude-Sorted where each bell's data are in separate files. The columns are ordered FREQUENCY, AMPLITUDE, DECAY, PHASE, and each row corresponds to a different vibrational mode.

Parameter-Specific-Files where each modal parameter (frequency, amplitude, decay, and phase) is presented in a separate file. In this scheme, the data are organized as a matrix where each row corresponds to mode number and each column corresponds to an individual bell. When a bell has a small number of modes, the extra rows are padded with NaNs.

You can download the modal data here.

Note: The second lowest bell does not physically exist in the Lurie Carillon and our numbering scheme takes this into account in jumping from bell number 0 to bell number 2 before continuing sequentially up to 59.

The data were analyzed by Elliot K. Canfield-Dafilou and Kurt J. Werner.

The 60 bells of the Lurie Carillon were recorded and edited in October 2016 by Isaac Levine with the assistance of Ashton Baker, Rowena Ng, Rachael Park, and Anjana Rajagopal and the support of Tiffany Ng (UM Organ Department and John Granzow (UM Department of Performing Arts Technology).
