The Michigan years

Intonation, invention and musical participation. Recovered pages from Alex Ruthmann’s sruthman website, captured between 1999 and 2002.

01 / Captured 2000Intonation & learning toolsListening, tuning & practice

The Comma Destroyer tuner and Tuning with Fifths recordings made intonation something to hear, adjust and explore. This page also records lectures and proposed handheld designs.

Captured 27 May 2000. Original publication date not established. Recovered 14 October 2026.

Completed software, recordings and proposed future work are described together in the original text. The technology CV dates Comma Destroyer to 1998; the capture itself is from 2000.

COMMA DESTROYER INTERACTIVE TUNER 2.0 SOFTWARE

This is software I wrote at the request of saxophone

professor Donald Sinta and wind conductor H. Robert Reynolds

as a training tool for conductors and students to visualize the "beating"

effect of out of tune notes. The software generates intervals and

chords randomly out of tune for students to adjust by ear and then test

against a reference. Further versions will implement listening to

a live instrument and giving feedback through additional source code written

in MSP. As well, several historical temperament presets will be implemented

to provide an aural reference for students.

TUNING WITH FIFTHS - A CD BASED INTONATION

IMPROVEMENT SYSTEM - (Vol. 1 and 2)

This is a CD I produced based on research I conducted

with Profs. James Tapia and Donald Sinta of the Univ. of Michigan.

We wanted a system that students could free them from the computer and

take into the practice room. Students play simple melodies, arpeggios,

drone tones and scales against 37 tracks of just-intoned fifths ranging

from E-flat 1 - E-flat 4. The reference timbre is a modified triangle

wave that models the harmonic structure of most wind instrument timbres

generated from my Comma Destroyer software. When a student practices

their note against a pure root and a fifth, the beats are easier to hear

and fix. Volume 1 has only perfect fifths, while the upcoming Volume

2 has seconds, thirds, fourths, sixths and sevenths in major, minor, augmented

and dimnisnished forms for advanced practice. The CD will soon be

packaged with an Intonation Handbook for Wind Instrumentalists

that I am currently writing.

The current price is US$20 (includes shipping

in the US) and there are discounts for bulk orders. Email sruthman@umich.edu

TUNING AND TEMPERAMENT FROM PYTHAGORAS TO

PARTCH: A BRIEF HISTORY, MUSICAL EXAMPLES AND EXCERCISES TO IMPROVE INTONATION

This is a lecture/presentation that I give to

each of the major performing ensembles and conducting classes each year

at the University of Michigan. I have also given modifications of

this lecture to the Michigan Music Educators' Conference and the regional

Conductor's Guild conference.

INTONATION HANDBOOK FOR WIND INSTRUMENTALISTS

This is a comprehensive handbook for wind instrumentalists

that I am currently in the process of writing. This

handbook will include chapters on the intonational tendencies of the major

wind instruments, provide historical information on the evolution of tuning

and temperament, performance practice of music conceived in various tunings/temperaments,

and discuss outside factors that affect intonation such as humidity, warm

up, and performance with piano, strings and fixed pitch percussion.

HAND HELD JUST INTONATION TUNER

In the prototype stage is a hand held just intonation

tuner that I've designed. This product combines all the features

of my tuning software and audio CD into a portable intonation/ear training

tool that a student can take anywhere. The specs are below.

Électronic Performance Interfaces

EZ I/O

- The Key to my Projects

http://www.ezio.com

The EZ I/O

is a sensor interface board for use with PC, Mac, SGI, and UNIX platforms.

It provides the user with an easy and cost effective way to create interactions

between a computer and the environment with the use of attached devices.

It communicates with the computer via serial communications and also has

a USB option in development. I worked with Art Professor Michael

Rodemer, the developer of the EZ I/O, on developing a software interface

for music through Opcode's Max. Since writing the Max external people

at the U of M and beyond have been able to trigger samples depending on

how far away your hand is from a source of light... or having the timing

of a strobe change based on how fast the people around a motion sensor

are moving. Below are several projects of mine where I've used the

EZ I/O or related microcontroller technology.

Selected Music Compositions

Blues for Stanley (Kubrick):

This

piece was composed as the final project for my Digital Sound Synthesis

class at Michigan. For years, I had admired Stanley Kubrick's use

of music in his films and after hearing of his passing, I wanted to write

an elegy. I used 3 sampled sources as core material for the piece:

a cadenza from a Mozart horn concerto and the themes to two 1970Çs TV shows:

Barney Miller and Sanford and Son. In MSP, I pieced

together various self-authored code as well as borrowed granular synthesis

code from people around the Internet. I morphed, convolved, stretched

and compressed the 3 samples and arranged the final product in ProTools.

I tried to imitate Ligeti-esque ethereal textures, that pervade several

of Kubrick's films, as well as capture some of the ironies between source

material and the end result while keeping a "bluesy" feel in tribute to

the great director.

(Audio CD enclosed)

Shards:

I wrote

this piece for full orchestra during my senior year of high school.

I had been studying composition with Prof. James Mobberley of the University

of Missouri-Kansas City. He was composer-in-residence at the Kansas

City Symphony and proposed that the Symphony do a concert that included

student works. I was then asked if I would write a piece for the

them and of course I agreed. This was a tremendous learning experience

that not only honed my Finale chops, but gave me an opportunity, especially

as a high school senior, that all composers dream of. So over

the next 2 months I honed my shattered variations on a simple theme and

on March 5th and 9th, Shards was performed by the Kansas City Symphony.

The class was introduced to the

myth

and concept of the Labyrinth with readings from Ovid and anonymous Middle

English texts (labyrinthian epic poems). The class also discussed subjective

points of resonance within the myth, in an attempt

to deepen the meaning of the myth as well as examine itís metaphorical

power and significance. The class was then asked to make an artwork, utilizing

the School of Music pond as a Canvas/Soundboard/Theatre.

A remote controlled boat carrying

a flashlight is guided through a wooden labyrinth floating upon the pond.

At four points throughout the labyrinth are totems. These totems have photosensors

attached to them that, when triggered by the flashlight from the boat,

add a unique sample to the ambient background music. The finale to the

piece is the central totem, the Minotaur. Three showings of the piece took

place at the University of Michigan School of Music Pond on Wednesday and

Thursday, October 28th and 29th. The final showing was on the evening of

the 29th, with the addition of candles floating on the labyrinth, glowsticks

and Day-Glo paint for the boat, and members of the Creative Arts Orchestra

performing live near the pond.
