Automatic Extraction of Expressive Timing Using Dynamic-time-warp Alignment of Score and Performance by Brian Highfill
Timing dynamics of musical performance is an important aspect of musical prosody. Tempo rubato is popularly used as a metric to analyze this type of musical expression. This is extracted most accurately from the manual annotation of note onsets times and is cumbersome and impractical for batch processing. This project aims to solve the problem for pieces with known score by automatically aligning a recorded performance to a synthesized MIDI representation following the dynamic time-warping approach of the MATCH algorithm.

Analysis of Glissando Characteristics in Trumpets and Trombones by Abhijit Bhattacharjee
The automatic identification of musical instruments in an audio file is among the most difficult tasks in music information retrieval (MIR). One of the most serious challenges in automatic instrument identification is when two instruments sound very similar to each other.Here, I have chosen to focus on analyzing the distinguishing differences between trumpets and trombones, by analyzing the glissando present between note or pitch transitions in musical performances. My hope is that this characteristic can be used in a machine algorithm to increase classification performance significantly.

Expressive Instruments - from Spanish Piano Music to the Spanish Guitar by Chandrasekhar Rajagopal
Much work has recently been done on musicians' use of expressive timing to communicate musical ideas - minor fluctuations in tempo to convey expression. This project will explore how the motivations, challenges and execution differ for contrasting instruments. 12 performances of Enrique Granados' Spanish Dance no.5 on Classical Guitar and Solo Piano will be analyzed for this purpose - the work was originally written for solo piano, but has since gained great popularity for its guitar transcription.

Analysis of Differences in Violin Performances Over Time by Balamurali Ramasamy Govindaraju
Music like every other thing has gone through its fair share of evolution.This would have definitely contributed to the changes in the style of performance. We could certainly notice a difference in how the music sounds between performances of same piece that were performed decades apart. This project project tries to address or identify the changes in violin performances over time using signal processing techniques.

Assignment of Definite Times of Day - Rhythm Analysis in Indian Classical Music by Kamlesh Lakshminarayanan
Indian classical music tradition ascribes certain ragas to particular times of the day. This project considers music from different times of the day: morning, afternoon, evening and night and attempts to find rhythmic commonalities in each one of these groups. I seek to answer the question: Does the time theory of ragas have an impact on the way the percussionist performs?

Regional characteristics and differences of some Chinese folk music by Bo Li
This project studies characteristics and differences of some Chinese folk music based on the regional classification. Some representative folk music in one collection is analyzed. Their tempo, score intervals, and nPVI are compared. The characteristics and differences are discussed with consideration on psychological and cultural factors in specific regions.

Music and Speech

Mapping Recorded Speech to Expressive Performance by Isaac Schankler
There is a growing body of musical works in which live musicians mimic or accompany recorded speech. In almost all of these works, the musician(s) must follow the recording, restricting their expressive range. What if instead, the recorded speech could be warped in time to follow the expressive performance of a live musician? This project employs free and commercially available software to accomplish this with two musical works (Peter Ablinger's Voices and Piano and an original composition) as proof of concept.

The Rapper's Rhythm - A study on the different tempi and rubato tendencies of different rap artists by Jeremy Yuan
Rap artists strive to sound different to make themselves unique to the listener. Given a steady beat, a rap artist will weave their words along in their own fashion. In this project, I study the tempo and rubato that different artists in a collaboration song use on their words. The beat may be constant, but the verse delivery most definitely is not.

Music to Dance - Correlating Different Performances by Ravi Nitin Balajee
Dance to music. Dance steps are choreographed to suit the music being played. Different music might share a similar rhythmic pattern. In this project, I study the patterns in music using tools used in class and try to match different music to a given dance performance. That is, match Music to Dance. I intend to provide the part of music that best matches with the dance. I am using videos of dance performances on YouTube for this project.

Analysis of Fantasy Genre Film Scores by Wesley Yeh
This project explores the relationship between movie soundtracks and its corresponding scene. I analyze scores within the same film, and between films and composers, through subjective interpretation and technical analysis of tempo and loudness.
