An examination of the keyboard technique of Bach, Haydn, Chopin, Scriabin and Prokofiev
Master's Project (M.Mu.) University of Alaska Fairbanks, 2016In this research paper, I will explore the keyboard technique of each composer presented in my recital: J.S. Bach, Franz Joseph Haydn, Frederic Chopin, Alexander Scriabin and Sergei Prokofiev. I hope to elucidate the physical approach used by each composer, and show in turn how that same approach influenced the music of each composer by analyzing the pieces performed in my recital. To understand the distinct technique of the composers, it is important to know some context. The instrument each composer wrote for necessarily influenced their technique and resulting composition. However, the instrument cannot explain every facet of technique, and it becomes necessary to understand the underlying aesthetics of technique. Moving chronologically from Bach to Prokofiev, a general trend of expansion in the use of the hand and arm will be seen throughout. Keyboards became louder and heavier in touch and the hand faced greater reaches in every generation. The technique of Bach and Haydn was largely focused on compact and relaxed hands with distinct finger movements, while Scriabin and Prokofiev at the other end require sweeping gestures that occupy the entire arm. However, it would be too easy to present this progression as a story that technique is only getting better and better, implying that the older composers were inferior to the later. That is simply false. Instead, extended study of each composer shows that many technical principles are universal. The baroque keyboardists were likely playing with more weight than popularly imagined and one cannot play Scriabin with mittens on the hands
Social decision-making driven by artistic explore-exploit tension
We studied social decision-making in the rule-based improvisational dance
, where dancers make in-the-moment compositional
choices. Rehearsals provided a natural test-bed with communication restricted
to non-verbal cues. We observed a key artistic explore-exploit tension in which
the dancers switched between exploitation of existing artistic opportunities
and riskier exploration of new ones. We investigated how the rules influenced
the dynamics using rehearsals together with a model generalized from
evolutionary dynamics. We tuned the rules to heighten the tension and modeled
nonlinear fitness and feedback dynamics for mutation rate to capture the
observed temporal phasing of the dancers' exploration-versus-exploitation.
Using bifurcation analysis, we identified key controls of the tension and
showed how they could shape the decision-making dynamics of the model much like
turning a "dial" in the instructions to the dancers could shape the dance. The
investigation became an integral part of the development of the dance
Deep Learning Techniques for Music Generation -- A Survey
This paper is a survey and an analysis of different ways of using deep
learning (deep artificial neural networks) to generate musical content. We
propose a methodology based on five dimensions for our analysis:
Objective - What musical content is to be generated? Examples are: melody,
polyphony, accompaniment or counterpoint. - For what destination and for what
use? To be performed by a human(s) (in the case of a musical score), or by a
machine (in the case of an audio file).
Representation - What are the concepts to be manipulated? Examples are:
waveform, spectrogram, note, chord, meter and beat. - What format is to be
used? Examples are: MIDI, piano roll or text. - How will the representation be
encoded? Examples are: scalar, one-hot or many-hot.
Architecture - What type(s) of deep neural network is (are) to be used?
Examples are: feedforward network, recurrent network, autoencoder or generative
adversarial networks.
Challenge - What are the limitations and open challenges? Examples are:
variability, interactivity and creativity.
Strategy - How do we model and control the process of generation? Examples
are: single-step feedforward, iterative feedforward, sampling or input
manipulation.
For each dimension, we conduct a comparative analysis of various models and
techniques and we propose some tentative multidimensional typology. This
typology is bottom-up, based on the analysis of many existing deep-learning
based systems for music generation selected from the relevant literature. These
systems are described and are used to exemplify the various choices of
objective, representation, architecture, challenge and strategy. The last
section includes some discussion and some prospects.Comment: 209 pages. This paper is a simplified version of the book: J.-P.

Query-based Deep Improvisation
In this paper we explore techniques for generating new music using a
Variational Autoencoder (VAE) neural network that was trained on a corpus of
specific style. Instead of randomly sampling the latent states of the network
to produce free improvisation, we generate new music by querying the network
with musical input in a style different from the training corpus. This allows
us to produce new musical output with longer-term structure that blends aspects
of the query to the style of the network. In order to control the level of this
blending we add a noisy channel between the VAE encoder and decoder using
bit-allocation algorithm from communication rate-distortion theory. Our
experiments provide new insight into relations between the representational and
structural information of latent states and the query signal, suggesting their
possible use for composition purposes
Project management and music in education and related fields
Project Management (PM) is a well-established field of research with the scope of inquiry now ranging far beyond the industrial and corporate sectors from which it first emerged. Starting from the premise that PM expertise is a valuable professional attribute and life skill of relevance to many if not all educational disciplines, questions emerge both as to how relevant techniques can be most effectively applied in educational contexts, and how insights might potentially be drawn from the study of different disciplines to enrich the PM profession. This paper focuses initially on higher education (specifically university level study) within the United Kingdom (UK) and other countries, and provides a contextual analysis of the discourse and practice of PM in undergraduate degree subjects. Discussion then narrows in on the discipline of music, as a specific context for consideration of PM through the educational and professional continuum. Identifying a relative absence of explicit PM theory or terminology in the vast majority of degree subjects at least in the UK, there is, nevertheless, an underlying presence of project-based activity at least implicit in all university education and music, in particular, presents a distinctive example of a creative, cultural, educational, where PM is an integral component and experience of subject and discipline. This paper concludes by identifying significant value in the development of a more explicit approach to PM in educational contexts and considerable scope for the development of professional relationships between PM organizations and the higher education sector in particular
