A Conceptual Framework for Technology-Assisted Music Learning

Digital technology has allowed the expansion of our immediate worlds. The evolution of internet (from phone line-based internet to the most current 3G and 4G) have allowed us to develop networks that are increasingly easy to monitor. For that and many other reasons, new digital technologies have become highly pervasive in our lives (at least in most urban settings).

We use digital technologies often in our spare time to socialize and for entertainment, but we also use it to organize our work, to expand our networks, and for education purposes improving our access to information and educational software. Making technology an integral part of the learning process afford the students more control over the way that they learn and therefore more adaptability to individual’s needs (Rusell & Sorge, 1999, as cited in Bauer, 2014, p. 7). Digital technology has also have considerable impact on music, facilitating the development of new synthetic instruments, digital audio recording and processing technics and software, and distribution.

Though technology, pedagogy, and content are fields of knowledge in their own right, educators must understand how they intersect.  This intersection point is referred by Mishra and Koehler (2006)  as Technological Pedagogical and Content Knowledge (TPACK) (as cited in Bauer, 2014, p. 12). An educator must know the content of the subject being taught, educational strategies based on learning theories, and how to use technology in general, but all of this fields interact as the teacher must realize which strategies suit better certain contents and ways of learning, and the affordances technology provides for education, and ultimately, the affordances technology provides us with for the learning of the specific subject matter, in our case music.

The following video is an introduction to the TPACK model:



Let us say that a music teacher is trying for the students to learn music notation. A traditional approach is to directly teach the values of rhythmic figures and the place of notes in the staff. The teacher must understand that not all students learn in the same ways, and some students might need more visual stimuli to associate with the synesthetic implications of traditional music notation (e.g. pitch is associated with height, time is read from left to right) and to understand elements that are not necessarily conveyed literally in a score (e.g. rhythmic figures remain isochronal independently of their relative placement within the left-to-right time framework).

A strategy might be to directly use visual and kinesthetic elements, such as body movement to perform rhythmic patterns and use relative levels of height in relation to the floor either to suggest pitch or dynamic levels. A more technological approach can integrate software that blend sound with a graphic interface. Many computer programs use MIDI protocol to inform the generation of sound and have a graphic interface to make the manipulation of sound parameters an intuitive process. Software like Fruity Loops and Cakewalk provide a graphic environment fairly intuitive.



But technology afford us much more specific tools. Pixel Tune (Punto y Tono), for instance, is a small application that features drawing and painting tools, which one can use in a type of canvas, and translates this bit map into MIDI data which is interpreted by the sound card in your computer to produce sound. Pixel Tune can be used for students to explore and internalize the ways sound can be conveyed graphically into notation. Additionally, the use of such a software can foster creativity and encourage the use of mixed media which can be artistically valuable in both visual and musical ways.  To recognize how technology can have a substantial impact as a pedagogic strategy for teaching the specific topic of conventional and unconventional music notation, plus additional affordances provided by the technological tools regarding the subject matter, constitute an example of the TPACK of a music educator. 

Additionally, the connective capabilities of internet, thanks to social media applications and websites such as Facebook, Twitter, Blogs, and so on, allow the development of networks that we can use to inform our work, obtain and provide feedback, and interact as participants in long distance and/or culturally diverse projects.

Pixel Tune

One of the most used technologies in audio software is the MIDI technology. Musical instruments digital interface (MIDI) is a protocol that allows electronic instruments to send and receive data to and from either other electronic instruments or MIDI devices and computers. MIDI files are not actually sound, but sets of data that set the specific parameters to be reproduced by a MIDI capable sound system.

Most of today's computers have MIDI capable sound cards, and they have drivers to translate MIDI messages into sound. This feature is very convenient, since it allows the use of very small software to produce audible sound. Many applications (computer programs) use this protocol to provide us with a whole world of sound, some with their own MIDI sound-library. Some other applications use the system MIDI interface directly, and even if the quality is not the best, there is plenty to be achieve with them.

One of those applications is called Pixel Tune (Punto y Tono in Spanish). Pixel Tune, created by Manuel Jander and Mario Arenas, is a mixed-media software that allows the user to use a series of graphic tools to draw and paint (just similar to the famous Paint, which is part of Microsoft Windows). The difference is that Pixel Tune uses the canvas as an interface to write MIDI data, which can be translated into sound by a playback button.



The playback option reads the file from left to right in a span of time that can vary according to the speed that we want. Up and down are translated into tempered chromatic pitch. Different colors are the different MIDI sounds, and the intensity of the color (brightness) is interpreted as MIDI velocity (or volume). When the file is played back, one can see the painting in full screen view, and so the music and the paint are displayed simultaneously.

One of the things I like the most is that there are a variety of tools, such as lines, shapes, spray, and a randomized paint. The result is not always tonal (actually most of the time it is not) and shapes such as squares produce interesting clusters of sound. You can use it directly to paint and have the paint interpreted as sound, or you can use it to consciously compose a piece, and you can use it conscious of those two aspects. The canvas scrolls to the right, so you can actually draw more than you can see in the space of a single screen, which is a feature that I have not seen in other apps that blend music and painting. And since the app uses the integrated MIDI capabilities of your computer, both the interface and the files are very small sized.

In terms of pedagogic application, Pixel Tune is a very useful tool that can serve various purposes. One of the most important might be to foster creativity and open-mindedness towards atonal music. Another element might be the development of a graphic language to create music and a step towards conventional and unconventional music notation.

In the following video, we can see students using the software.



Here is a link to download the software, which unfortunately is only available for Windows. The download is a compressed folder.

http://sourceforge.net/projects/pixeltune/

Once you have the files, extract them into  a folder and open the .exe file.

Dr. Mario Arenas, the main developer of this app, is a PhD. in education science, and Mr. in Arts and Composition. He teaches at Universidad de La Serena, Chile.

Hello World!

Hello world,
This blog is a requirement for an online course called Technology Assisted Music Learning, at the University of Florida.
I will be posting updates every week (I hope) with relevant information and resources (such as discussions and bibliography) as the course goes by.
I hope this blog will be useful for me not only at the present, but also in the future, and I hope it can also be useful for others.
People an openly post and add to the discussions, and if there is anything more sensitive that can be discussed, I would be happy to provide contact information upon request.
The following are a couple of videos on my relationship with technology and sound.

Have a great week!!!
