It was this success that really marked the turning point in the band’s musical standards. Players were attracted to the Band and progress was maintained even during the difficult years when the instruments changed from high pitch to low pitch. Initially this was achieved by adding longer slides, then by purchasing new instruments, helped by the support of the mineworkers and steelworkers in the area.

It was during this period that the Band promoted their Annual Concert series at the Workmen’s Hall Tredegar, inviting two well known operatic singers (male and female) to share the platform with them. Each of these concerts enjoyed full audiences. During the summer months the Band were engaged by the local council to play in the Bandstand in Bedwellty Park, on twelve consecutive Sunday evenings from 7:30 p.m. to 9:00 p.m. Audiences came directly from their church and chapel services to listen to the Band, with many visitors coming from the surrounding districts. To play a different programme each week including request items was a challenge for the Band and was beneficial to the players’ sight reading abilities. At this time, the Band was rehearsing three times weekly, normally Tuesdays, Thursdays and Sundays. An unusual engagement for the band took place in 1959 when they led the singing of “Happy Birthday” to celebrate the 100 th Anniversary of the famous Town Clock. The circle housing the clock was thronged with Civic dignitaries, choirs and members of the public.

Throughout the Bandstand season, the Band rehearsed for one hour prior to each concert, in order to maintain their rehearsal schedule. Players prominent during this period were Brian Vaughan (Cornet), the Beeson Brothers – Brian (Cornet) and Gordon (Trombone), Albert Gould and Dan Stephens (E Flat Bass), George Davies (Bass Trombone) and Godfrey Thomas (B Flat Bass).

Wednesday evenings were set aside for the Brass Learners classes, the beginners being directed by Ivor Powell (brother of the well known T. J. Powell), with Con Buckley teaching the more advanced learners, several of whom were allowed to attend rehearsals to ‘sit-in’ with the Band. During the late 1950’s, Monmouthshire County Council started developing their progressive Youth Music Policy, so funded one evening’s music lessons per week for Bands that could demonstrate satisfactory attendances and progress. As part of this measure, the Annual Gwent Youth Brass Band Contest was started and has certainly flourished. Initially, the contest consisted of a test piece (fixed), together with an own choice march and hymn tune. Tredegar were always very successful, regularly winning the contest from its inception throughout the 1960’s and of course, continuing this pattern of success through to almost the end of the 20th century.
