 My project involves 3 separate parts
+) '''Fix widget bugs''' - There are several widgets in Music Blocks. As reported on github
+repository  <nowiki>https://github.com/walterbender/musicblocks/labels/widget</nowiki> , there are around
+bugs reported currently. I think there would be another 10 bugs related to widgets which
+would be reported during summers. I am planning to remove 2-3 bugs per day. Most of thebugs involve pitch-time matrix, tempo, timbre, filters, rhythm ruler. Most of bugs are easy
+and they would be fixed in around 10 days. Other bug reports involve adding some
+functionality and are actually enhancements.
+) '''Pitch tracker -''' It involves making a widget which would record sound, process it to find
+fundamental frequency for every small segment, and then choose blocks (whose frequency
+is closest to fundamental frequency of each segment), and then use these blocks to code
+the recorded sound in Music Blocks language.
+I chose to use fundamental frequency because it can be calculated in real time and is easy to
+calculate as well. For calculating fundamental frequency I will be using autocorrelation as
+feature vector. Autocorrelation is correlation of a signal with its delayed copy.
