The Meertens Tune Collections (MTC) and the Essen Folk Song Collections include various data sets with melodic data. The melodies are provided in Humdrum **kern encoding and as MIDI sequences. In many cases, a representation of the melodies as sequences of feature values is needed rather than encoded scores. The present dataset provides such feature sequences. It is accompanied by a Python module that offers functionality to load and filter the sequences: MTCFeatures. The documentation of MTCFeatures contains a detailed description of the features. The following melody collections are included: MTC-ANN-2.0.1 - A small set of 360 richly annotated melodies from Dutch sources. MTC-FS-INST-2.0 - A large set of c. 18 thousand melodies from Dutch sources. ESSEN Folksong Collection - A set of more than 8 thousand folk song melodies mainly from Germany. For more information on the contents of the Meertens Tune Collections, please visit http://www.liederenbank.nl/mtc/. For the Essen Folk Song Collection, the features were extracted from the **kern files in the zip-archive as provided by the Center for Computer Assisted Research in the Humanities at Stanford University (https://kern.humdrum.org/cgi-bin/browse?l=/essen).
