Videoconferencing and Remote Music Instruction
Videoconferencing allows two (point-to-point) or more locations (multipoint) to communicate by simultaneous, interactive video and audio transmissions. An increasing number of schools across the country teach music technology classes via online classes locally and long-distance simultaneously.
Products for Videoconferencing Instruction
There is a wide variety of videoconferencing software programs to choose from. Some are freeware and others have a per-month paid subscription. Some are point-to-point, which are restricted to only two computers, while others offer multi-point connectivity for up to 100 users. Product features vary as well, but all of them give you a free-trial period, often 30 days, during which you can do actual field-testing.
Virtual High School
The Virtual High School in Maynard, Massachusetts has enrolled over 63,000 students from 700 member schools with 500 teachers from over 31 states and 34 countries since 1997. Their online classes include composition, popular music, AP Music Theory, and others. For example, their AP Music Theory has gone from one section in 2010 up to five or more sections because demand for the course is so high. This year, they replaced a CD-ROM software component with a fully online, browser-based app. They also added collaborative activities through blogs and wikis and are in the process of switching to eBooks and re-mapping assessments to better match AP Exams.
Indiana University-Purdue University Indianapolis
Fred Rees, chairman of the Department of Music and Arts Technology, at Indiana University-Purdue University Indianapolis, is a pioneer in videoconferencing with music education and technology. Since assuming his appointment in 1999, he is credited with creating their B.S. in Music Technology program. He and G. David Peters expanded their M.S. in Music Technology program by employing Internet-based video streaming technologies. He first began videoconferencing in the early 1990s at the University of Northern Iowa (UNI), where he placed the M.M. in music education degree program over the then new Iowa Communications Network (ICN) interactive television system.
Rees makes a distinction between videoconferencing and videostreaming. “Videoconferencing, which I did when I was at UNI, is what you experience with Skype or FaceTime. However, in addition to seeing and talking to one another, the more advanced resources of a system like the ICN also allows the instructor to play music, share computer images, display printed material, and interact between the instructor and students at multiple sites and on campus simultaneously. Videostreaming also has these capabilities, but usually lacks the bandwidth to provide high quality audio and video. Also, a videostreaming session may be a one-way transmission to viewers, with limited or no opportunity for them to respond in real-time.”
The entire MS in Music Technology program is videostreamed to online students simultaneously with on-campus students sitting in class. “We use Adobe Connect, a videostreaming tool that is becoming common in collegiate institutions. It enables online students to see and hear the instructor or students in the classroom and to respond via a chatroom. Additionally, the instructor can share his or her desktop with the class or pull up online students’ desktops when they are giving presentations. If desired, I can change settings for online students to be seen and heard, when they want to join the class that way. In conjunction with Adobe Connect, we also run iStream, an Indiana University videostreaming tool that provides higher quality audio and video going out to students, but without the capability for students to respond over it. We videoarchive all classroom proceedings in both Adobe Connect and iStream for future viewing.
“We employ OnCourse, also developed by Indiana University, as the course management system. It contains videostreaming links and has its own email system, forum, chatroom, grade book, and testing resources. Six faculty members teach in the MSMT program using these tools. I personally use Skype and FaceTime with students outside of class meetings for consultations. I also employ Cisco Jabber Video for multipoint videoconferencing beyond the classroom with colleagues worldwide. It enables multi-point connections with good quality audio and video, and a presentation feature from any site for applications that reside on a computer desktop.”
Synchronous Interactive Online Instruction
Since 2006, I have been teaching music technology workshops for the Technology Institute for Music Educators (TI:ME), which includes multipoint interactive instruction with videoconferencing for each workshop. Content varies from notation, sequencing, and electronic keyboard apps to web development and integrating technology within the classroom music curriculum.
This past school year, I was teaching at Shandong University in Jinan, China and, with videoconferencing, I was able continue my weekly private lessons in Denver, Colorado. And even though I was 9,000 miles away in China, my students were still prepared to win countless seating challenges, get selected in all-county and college honor bands, and be awarded full-ride music scholarships. One important tip is that the music for each student’s lesson was scanned into PDF files before each session, so I could view it and use my cursor to point out where improvements needed to be made. This helped give real-time instructional feedback.
Remote Recording Sessions
Hiro Morozumi is a jazz pianist and composer from Tokyo, Japan who has studied at the University of North Texas and travels the world as a performing artist. Using videoconferencing, Morozumi recently recorded musicians in Japan and the USA to produce a soundtrack designed to be the background music in Japan’s 7-Eleven stores. “We used Skype video chat so I could see how the mics were placed by my friend playing the saxophone, flute, and so on,” says Morozumi. “Our three-way group chat mode on Skype included me on desktop in Los Angeles, a laptop in Tokyo, and an iPhone in Tokyo feeding back the laptop screen.”
He continues: “We used Presonus Studio-One software. This cut comes with surprisingly generous features, even on the free version. It perfectly served our simple recording task needs. We got good tone from our inexpensive but carefully chosen equipment: Audio-Technica AT2020 mic, Art Studio V3 pre-amp, and a Roland UA-25EX audio interface. One can get all of these for less than $300. Our secret weapon was a vacuum tube we used to replace the default Chinese part that came in the Art Studio V3 preamp. The Russian-made Electro-Harmonix 12AX7 tube is around $13, but this made the $70 pre-amp comparable to equipment worth $1,000, in my opinion.”
When it came to transferring the files over the Internet, Morozumi and his team experimented with various file transfer protocols for large session files (350MB per song). “The fastest and most reliable method was to upload using freeware Filezilla via FTP to web hosting I subscribed to from godaddy.com to host my website,” he says. “I pay only about five dollars a month and get total of five GB, so I can easily make room for one or two GB for file-transferring for production purposes. Another effective way to transfer files was using www.justbeamit.com. It’s not as fast as FTP, and requires both interacting computers to keep a browser open during the transfer, but it comes in handy whenever a quick transfer is necessary while we’re on Skype. File transfer on Skype is slow and not very useful for large files. “ You can hear the results of Hiro’s remarkable videoconference recording sessions and several other schools at: www.kuzmich.com/SBO1213.
