Instructions for Purchase and Use: You can buy individual access to each video for unlimited use, rent it for 72 hours, or purchase access to all videos in each section related to the work for a full year. To buy complete access to the video section, click on the three dots and select "Subscribe," or open/expand the video section by clicking any video, then find the "Subscribe" option at the top. To purchase individual video access, with the sample video selected, find the "Buy from..." button and choose whether you want to buy for unlimited access or rent for 72 hours. Alternatively, you can go directly to the currency icon in the video bar, click it on the desired video, and access the same options. In any case, you’ll need to be logged in or create an account. Remember, to watch/play the purchased video fully after buying, you must always be logged into the account you used for the purchase; otherwise, only 20-second previews will be shown. If you have any questions, please contact us via Chat or WhatsApp for support, both for purchasing and resolving issues. In the video section for each work, you have playback options in two tunings: 440Hz (modern standard tuning) and 415Hz (most commonly used for historical instruments). There are also several rendered options for fast movements at "user-friendly" tempos to support progressive development. These are also suitable for final performance in more moderate tempos, allowing for deeper exploration of ornamentation, articulation, and dynamics. If you need specific tempos or a particular arrangement/instrument combination, feel free to contact us, and we’ll produce them as feasible and add them to the collection. We are continually updating and enhancing the playbacks based on new possibilities and resources, as well as on user feedback, which helps us refine the content based on their experience.
