# Song Structure Timer MCP for AI Agents AI Agent Connect > Song Structure Timer calculates musical timing, section durations, and full song timelines based on BPM and meter. It helps producers and musicians plan arrangements and create precise recording references without manual math. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_FxBJs6caBgApUpAHbJlGI3mYWv6pCwaWg9V33ISC/ai-agent-connect - **Tags:** bpm, music-production, timing, songwriting, audio ## Description The Song Structure Timer is a precision utility for musicians and producers to calculate the exact timing of musical segments. You provide the BPM and time signature, and the tool finds the duration of beats and bars instantly. You can calculate specific section lengths and generate a complete, timestamped song timeline. This works for recording reference, arrangement planning, and mastering. It's one of the practical tools in the Vinkius catalog that actually solves a specific, recurring friction point in the studio workflow. It turns abstract musical ideas into concrete numbers you can actually use in your DAW or during a live session. You can stop pulling out a calculator every time you want to know how many seconds are in a 16-bar verse at a specific tempo. Instead, just ask your agent to map it out. It handles the conversions so you can stay in the creative zone. You can coordinate with session drummers or prepare mixes for mastering with a clear roadmap of your track's structure without the math headaches. You can quickly figure out where a transition should land or how much time you have for a bridge, making it much easier to communicate your vision to other collaborators. It takes the guesswork out of your arrangement and puts the focus back on the music. ## Tools ### get_bar_rhythm_metrics Calculate the exact number of seconds per beat and per bar based on your tempo. This helps you quickly check timing changes between different parts of a track. ### calculate_section_duration Find out how long a specific part of a song lasts in seconds. Use this to ensure your arrangement fits your vision without manual math. ### generate_song_timeline Create a full structural breakdown of a song with start times for every section. This provides a clear roadmap for your entire project. ## Prompt Examples **Prompt:** ``` How many seconds is a 16-bar verse at 120 BPM in 4/4 time? ``` **Response:** ``` At 120 BPM in 4/4 time, one bar lasts exactly 2 seconds. A 16-bar verse will last exactly 32 seconds. ``` **Prompt:** ``` I have a song at 95 BPM. Give me a timeline for an 8-bar intro, a 32-bar verse, and a 16-bar chorus. ``` **Response:** ``` Here is your timeline: * **Intro**: 0:00 to 0:19.4 * **Verse**: 0:19.4 to 1:14.8 * **Chorus**: 1:14.8 to 1:46.2 ``` **Prompt:** ``` How long is a 4-bar transition at 140 BPM? ``` **Response:** ``` At 140 BPM, a 4-bar transition lasts approximately 6.86 seconds. ``` ## Capabilities ### Get beat and bar durations Convert your BPM and time signature into exact seconds per beat and per bar. ### Calculate section lengths Find the precise duration of any song section based on its number of bars. ### Generate song timelines Create a full structural breakdown of a song with start times for every section. ### Map musical arrangements Build a timestamped roadmap of your entire track for easier planning. ### Verify recording references Check your audio segments against calculated timing to ensure they align perfectly. ## Use Cases ### Coordinating with a session drummer A producer needs to tell a drummer exactly where the bridge starts in a 100 BPM track. They use the Connector to generate a precise start time for the drummer to follow. ### Checking intro lengths A songwriter wants to know if an 8-bar intro is too long for a specific tempo. They use calculate_section_duration to get the exact seconds instantly. ### Mastering project roadmaps An engineer needs a timestamped list of every section for a complex mastering project. They use generate_song_timeline to build a full structural breakdown. ### Live setlist planning A live performer wants to see a visual breakdown of a song's structure for a setlist. They use the Connector to map out the timing of every section for a smooth performance. ## Benefits - Stop manually calculating beat durations when you need to know exactly how many seconds a section lasts. - Use generate_song_timeline to create a master map that you can share with other musicians. - Get accurate data for calculate_section_duration to ensure your arrangement fits your vision. - Use get_bar_rhythm_metrics to quickly check timing changes between different parts of a track. - Spend more time on the creative side of production instead of fiddling with a calculator. ## How It Works The bottom line is you get a perfect musical map without doing any manual math. 1. Provide your song's BPM and time signature. 2. Input the number of bars or beats for a specific section. 3. Get a precise duration or a full structural timeline. ## Frequently Asked Questions **Can Song Structure Timer help me plan my music arrangements?** Yes, it calculates exact durations for different sections. You can use it to figure out how much time you have for a bridge or transition based on your BPM. **How does Song Structure Timer work with my BPM?** It takes your BPM and time signature to give you second-accurate measurements. This helps you know exactly how many seconds each bar or beat lasts. **Can I use Song Structure Timer to get start times for my song?** Yes, it generates a full timeline with start times for every section. This is great for creating a roadmap that you can share with other musicians or engineers. **Is Song Structure Timer good for live music?** It's excellent for creating a reference sheet for performers. You can get a precise breakdown of the song structure to ensure everyone knows when each part starts. **Does Song Structure Timer work for any time signature?** Yes, you can provide any meter to get the correct bar and beat metrics. It handles the math for various time signatures automatically. **How do I calculate the duration of a single beat?** Use the `get_bar_ rhythm_metrics` tool. By inputting your current BPM and the number of beats per bar, it will return the exact duration in seconds for both a single beat and a full bar. **Can I generate a timeline for an entire song?** Yes, the `generate_song_timeline` tool allows you to input your BPM, meter, and a list of sections (like Intro, Verse, Chorus) with their respective bar counts to produce a complete timestamped breakdown. **How is the section duration calculated?** The `calculate_section_duration` tool takes the number of bars in a section and the duration of one bar (obtained from rhythm metrics) to calculate the total time in seconds, minutes, and a formatted MM:SS string.
