The purpose of this study was to determine a singing range of Korean geriatric populations, so that those leading senior citizen groups in singing could have a useful knowledge for efficient singing activities. The subject of this study consisted of 76 adults(42 females and 24 males) aged between 60 and 94, who were randomly selected from nursing homes and community centers in Seoul and Incheon. This study tested them individually by letting each of them try to match each note played on the keyboard by humming until reaching the point at which they could no longer sing comfortably. Following the Vocal Range Check Form(Kuhn, Wachhaus, Moore, & Pantle, 1979), vocalization began at E₄and proceeded downwards by chromatic tone and then upwards. The collected data included the lowest singable pitch (LSP), the highest singable pitch (HSP) and semitones between both terminal pitches. Statistical analysis indicated the following results: First, the average LSP and the average HSP were F#₃and A#₄ respectively, and the vocal ranges averaged 17 semitones. 75% of the subject of this study could sing at the range from G#₃to G#₄. Second, the mean vocal ranges for females and males were from E₃to A₄and from G#₂to B₃respectively. The vocal range of females was 2.7 semitones wider than that of males, representing the statistically significant difference by t-test(t=3.527, p=.001). Third, the older subjects had a slight tendency of a lower and narrower singing range according to the age, with a significant correlation between the HSP and the age. Findings from this study suggest that music therapist, activity directors and educators must have good transposition skills to fit compass of songs into this pitch range for efficiently leading elderly people in singing. In addition, it would be necessary to publish song materials to meet the vocal ranges and appropriate keys for Korean geriatric population.
