Plácido Domingo has a vocal range that is a weight between which two characteristics?
Spinto Spinto (from Italian, "pushed") is a vocal term used to characterize a soprano or tenor voice of a weight between lyric and dramatic that is capable of handling large musical climaxes in opera at moderate intervals. (Sometimes the terms "lirico-spinto " or "jugendlich-dramatisch " are used to denote this category of voice.)
Weighting curve A Weighting curve is a graph of a set of factors, that are used to 'weight' measured values of a variable according to their importance in relation to some outcome. An important example is frequency weighting in sound level measurement where a specific set of weighting curves known as A, B, C and D weighting as defined in IEC 61672 are used. Unweighted measurements of sound pressure do not correspond to perceived loudness because the human ear is less sensitive at low and high frequencies, with the effect more pronounced at lower sound levels. The four curves are applied to the measured sound level, for example by the use of a weighting filter in a sound level meter, to arrive at readings of loudness in Phons or in decibels (dB) above the threshold of hearing. (see A-weighting).
