Given the below context:  Holst's absorption of folksong, not only in the melodic sense but in terms of its simplicity and economy of expression, helped to develop a style that many of his contemporaries, even admirers, found austere and cerebral. 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. Vaughan Williams remarked that Holst always said in his music what he wished to say, directly and concisely; "He was not afraid of being obvious when the occasion demanded, nor did he hesitate to be remote when remoteness expressed his purpose". Kennedy has surmised that Holst's economy of style was in part a product of the composer's poor health: "the effort of writing it down compelled an artistic economy which some felt was carried too far". However, as an experienced instrumentalist and orchestra member, Holst understood music from the standpoint of his players and made sure that, however challenging, their parts were always practicable. According to his pupil Jane Joseph, Holst fostered in performance "a spirit of practical comradeship ... none could know better than he the boredom possible to a professional player, and the music that rendered boredom impossible".  Guess a valid title for it!
