![]() It investigates the whole of the interactions among the psychological, social and cultural factors that are at the base of any process of music production and reception. In the last decades Ethnomusicology – or better, Anthropology of Music – has gone beyond the mere study of the musical products of other cultures. I conclude by recommending further research to refine and deepen the understanding of creativity in community music and explore the implications for practitioners and researchers. ![]() My literature analysis shows that in the community music literatures there are references to several creativity rhetorics (democratic and political ubiquitous wise humanising creativity) and various areas of usage (musical processes, leadership processes and personal qualities). This chapter reviews current community music literatures on creativity and specifically examines the conceptualisation of creativity in relation to ten rhetorics of creativity (Banaji et al., 2010 Chappell et al., 2016). However, creativity in community music is not often explicitly examined or defined in the literatures. Group improvisation (Higgins & Campbell, 2010) and composition (McKay & Moser, 2005) are examples of community music approaches that are based on creative, collaborative group work. One of the underlying assumptions of community music as an intervention is that everyone has the ability to make music – all sections of the community have creative potential. In addition, it also uses the know-how and technology it develops in new research projects.Creative music-making is considered a key process in community music practice. In the “Joint Application Lab,” Fraunhofer ILT helps its customers to develop manufacturing processes. In this way, the energy distribution and, thus, the heat input within a parallelized beam distribution can be optimized. Thanks to the support of the Instruction and Research Department for Nonlinear Dynamics of Laser Manufacturing Processes (NLD) at RWTH Aachen University, Fraunhofer ILT has been able to simulate the processes completely. The heat distribution in the workpiece has become increasingly important when large average laser powers are applied and USP processes are scaled in speed and efficiency. The flexible liquid modulator eliminates the need for tool changes. The team of Hamamatsu and Fraunhofer ILT has investigated the surface and volume ablation with different beam profiles and focus diameters. In Aachen, the system with the new SLM has been in use for various processes and applications since May 2022. SLM enables high power in the application Hamamatsu received funding from the Japanese government to establish the new laboratory under the Cross-ministerial Strategic Innovation Promotion Program (SIP). The new SLM has been optimized for high average power and is currently being introduced to the market. The head is integrated into a 3-axis machine with a 150 W USP laser. This includes a scanner-based process head in which Hamamatsu's new high-power SLM is integrated. There, an industry-ready prototype is ready for the development of manufacturing processes. Together with the SLM manufacturer Hamamatsu, a “Joint Application Lab” has been set up at Fraunhofer ILT. “Joint Application Lab” at Fraunhofer ILT If the beam parameters are known and static, DOEs are the better choice due to their insensitivity. In series production, SLMs are advantageous if beam patterns have to be changed dynamically during the process. This applies to both the beam profile as well as the arrangement of the individual beams within a pattern. SLMs are particularly suitable for developing manufacturing processes that use USP laser radiation since the beam properties can be easily adapted and tailored. SLMs can dynamically change the phase pattern and, thus, also the beam matrix, while static DOEs can withstand higher average powers. This works dynamically with spatial light modulators (SLM) or statically with diffractive optical elements (DOE) made of glass. Phase masks are used to generate a parallelized beam patterns with a large number of partial beams from one incident beam. This approach is already being used industrially, particularly for two-dimensional laser material processing or for the generation of periodic patterns such as filters. One popular method to implement these large laser powers is to split the high-energy radiation into many individual beams. To increase the economic benefit of USP processing, research uses different hardware approaches to address the handing of increased high average laser powers with more than 100 watts, thus, upscaling processing speeds and lower unit costs. Ultrashort pulsed (USP) laser radiation can process virtually any material at the highest precision. ![]() Multi-beam systems are the key to scaling power, speed and costs Simulation – Laser Processes and Systems.Real-time measurement and control technology.
