VIDEO SHOT NOTE: For all of these videos below, higher rows are higher notes. (As I have some inconsistency on the site as to how I had the Spectratune set.)

VIDEO SHOT 1 (Spectratune monitoring the sound of a played recording of solo cello): This .wmv video file is a capture of what the Spectratune outputs on some Bach solo cello. (I have both the spectrum and the single-pitch running. The single-pitch will fail when there is the occasional two-strings being played. What I actually saw on the screen had a slightly higher frame rate--showing a little more of the short-term motion in the music. (The video capture software took a little less than every frame.)

VIDEO SHOT 1B (Monitoring sounds from my MIDI Music Analysis Software): .wmv video file.

VIDEO SHOT 1C (User Seeking Theoretical Ideas About Tonic/Dominant/Sub-Dominant Function): .wmv video file The user is experimenting with chords, trying to figure out what's going spectrally on with the Tonic, Dominant, Sub-dominant categorization of chords.

VIDEO SHOT 2 (Bach): This .wmv video file. C Minor prelude from a MIDI file played at a slowed-down pace through the Spectratune.

VIDEO SHOT 2B (Analyzing sound outputted from my Other Free Software -- ToneGen): This .wmv video file

VIDEO SHOT 3 (More Bach): This .wmv video file is of a section of a C# major prelude.

VIDEO SHOT 4 (Practicing Scales): This .wmv video file is a capture of a person practicing scales with the Spectratune,. The spectrogram happens to be turned on for this, which is optional, as the single-pitch detection is really all you need. (The person, unfortunately, has neither a good voice, nor an intotational gift!)

VIDEO SHOT 5 (Developing a Sense of Harmony in Singing): This .wmv video file shows a person trying to get a sense of singing harmony, using the Spectratune to show where they are against a triad they are trying to harmonize with. The triad is being played on a keyboard, with the spectrogram of the triad showing in blue. The triad is also being listened to in headphones. The person is singing along with the webcam mic, trying to get in harmony with the triad by listening, using the Spectratune for occasional guidance. The sing-along pitch is being displayed with they yellow arrow, which the person is using as an aid to figure out how to harmonize. The person is pretty successful getting into a nice harmony by listening alone, which happens to be when the yellow arrow is aligned with the center of any spectral peak for the triad. (The sing-along sound and thus the harmony involving the voice is not heard on the video, as the video-making software I used at the time I made this video could not capture it.)

VIDEO SHOT 6 (Showing Spectral Mode Both Devices:):
Since this is not a public domain recording (it is "Suzanne" sung by Judy Collins), I've hyper-respected the copyright and excluded the audio. This .wmv video file shows the recording, being played live, and then spectralized, in blue, and a person singing an octave below Judy Collins as the yellow-arrow (single-pitch), with also full spectrum in green. The key for the recording was easily determinable by comparing the spectral image to the recording to the sheet music (i.e. finding out what transposition of the sheet music it is), and is correctly superimposed in this example as F#. The melody in the vocal on the recording starts on the dominant in that 3rd octave up of the 6 shown, and is mainly between that and the tonic up, though it occasionally goes outside that range by about a step.
