MATLAB file containing the numerical values underlying Fig 3A, representing ERPs evoked by notes with relatively high versus low pitch surprise (Sp) for real and shuffled music, time-locked to note onset.

The data are stored as a 4D matrix with dimensions subject × condition × channel × time, where conditions 1–4 correspond to Low Sp (real), High Sp (real), Low Sp (shuffled), and High Sp (shuffled). Data can be opened using nonproprietary software such as R or Python. (MAT)
