Vox Organalis is a concerto for organ and orchestra. It employs an ensemble comprising the compliment of wind, percussion, and string instruments normally available within a contemporary symphony orchestra with augmented brass and woodwind sections. It is intended to be performed with a large organ such as might be found in a symphony hall or large church. The work is in two movements, and its intended performance time is twenty-five minutes. Use of the concerto format within Vox organalis results in a new approach to organizing the interaction between the solo part and the orchestral accompaniment. The organ part is notated in traditional metered notation, but the orchestral notation is organized in units of clock time (seconds). The horizontal spatial arrangement of the orchestral notation corresponds to the timing of the metered organ part. Pitch organization in Vox Oraanalis is derived from a twelve-tone row based upon the natural harmonic series. Several techniques of serial composition were used to organize and select elements of the tone row for use in the construction of the work. Use of the tone row for horizontal and vertical pitch structures provides unity to the pitch organization of the work. Vox Organalis is constructed in 12 sections which help define the formal shape of the work. Four of these sections comprise Movement I, and eight are contained by Movement II. The length of the formal sections are based upon the series of natural harmonic numbers from which the tone row was derived.

Historically, composers have used methods in addition to inspiration in writing music. Regardless of the source materials they used, composers ultimately rely on their musical sensitivity to inform the compositional decision-making. Discuses the rotational aspects of decimals that are created from certain prime-number denominators, and focuses on the prime number 17. Shows how these decimals can be transformed by converting them to different number bases. Looks at the Golden Proportion and its use in creating formal structures. Examines compositional and aesthetic issues arising from using number series to generate the pitches, rhythms, and sections in the Concerto for Organ and Orchestra. This process of composition reveals musical gestures that may not have been discovered using more intuitively based approaches to composition. Shows how musical sensitivity was necessary in shaping the numerically derived material in order to create aesthetically satisfying music.
