 This is contrary to the popular identification of Holst with "The Planets", which Matthews believes has masked his status as a composer of genuine originality.Against charges of coldness in the music, Imogen cites Holst's characteristic "sweeping modal tunes mov[ing] reassuringly above the steps of a descending bass", while Michael Kennedy points to the 12 Humbert Wolfe settings of 1929, and the 12 Welsh folksong settings for unaccompanied chorus of 1930–31, as works of true warmth.Many of the characteristics that Holst employed — unconventional time signatures, rising and falling scales, ostinato, bitonality and occasional polytonality — set him apart from other English composers.
